Abstract: A wireless telecommunication device conducts base station pages at large intervals, such as 30 seconds, rather than the more conventional 0.5 to 4 seconds. The network processes calls placed to that telecommunication device in accordance with an SMS (Short Messaging Service) type protocol rather than a conventional voice call protocol. Particularly, the network sends an SMS to the telephone indicating that a third party is calling (hereinafter termed a “pre-call SMS”). The pre-call SMS indicates the telephone number of the third party. The user of the telephone may call the third party back. In accordance with this protocol, the need to page at very short intervals so as to permit a telephone call to be established in “real-time” is eliminated. Therefore, the paging interval can be increased substantially, thereby substantially prolonging battery charge lifetime of the telephone.

Abstract: A telecommunication device is equipped with circuitry that can detect phenomena indicative or predictive of motion of the telecommunications device, such as GPS circuitry. When the circuitry determines that the telecommunication device is stationary, it controls the device to perform neighboring cell polling at relatively large intervals or not at all. However, when the circuitry determines that the telecommunication device is moving, it controls the device to poll neighboring cells more frequently.

Abstract: Methods of recovering data in a received signal sent in a communications media are disclosed. Composite channel impulse responses are first estimated. Channel-tap locations are then assigned to suppress the interference noises by sequential search schemes or heuristic search schemes based on estimated composite channel impulse responses. A sequential search scheme optimizes a predetermined design criterion in a sequential manner. Also described are recursive evaluations of the design criterion and the inverses of the noise covariance matrices based on the composite channel impulse response during a sequential search. A heuristic search scheme selects channel-tap locations based on a set of pre-selected channel-tap locations. The set of pre-selected channel-tap locations is determined according to the estimated composite channel impulse response. A method of estimating energy levels of known interference sources is also described.

Abstract: Methods of early-termination and output selection for iterative decoders are disclosed. A hybrid early-termination method combines the output-comparison-based method with the parity-check-based method. The hybrid approach is far more superior in termination reliability in either of the two individual approaches, without their disadvantages. The hybrid termination method effectively and reliably terminates the iterative decoding process, cutting the majority of the computational load while eliminating the degradation in the bit error rate (BER) and frame-error-rate (FER) performance due to incorrectly terminated frames.

Abstract: A system employs a modified Jakes' fading model to generate a fading signal having substantially equivalent autocorrelation values for in-phase (I) and quadrature-phase (Q) components. A Walsh transform may be applied to generate multiple, uncorrelated I and Q components, for multiple fading signals. A complex Rayleigh fading signal according to the modified complex Jakes fading model is provided by a generator having M pairs of I and Q paths. Each pair of I and Q paths includes a corresponding complex carrier generator 201 (M an integer and 1≦n≦M) generating a complex carrier signal with frequency, &ohgr;n, where &ohgr;n is cos ((4n−3&pgr;)/4M). Each of the I paths has a circuit that separates the real component of the corresponding carrier signal to provide a real carrier signal cos (&ohgr;nt). Similarly, each of the Q paths has a circuit that separates the imaginary component of the corresponding complex carrier signal to provide an imaginary carrier signal sin (&ohgr;nt).

Abstract: A circuit performs threshold normalization of accumulated transition probabilities for a given state of a state transition trellis in a maximum likelihood detector. Threshold normalization may be accomplished by comparison and setting of a single bit in stored transition probabilities. Threshold value comparison may be accomplished by comparing the bth bit of the stored transition probabilities if the threshold value is 2b. When all transition probabilities exceed the threshold value at a stage of the trellis, the transition probabilities are scaled, such as by subtracting the threshold value. Scaling may be implemented by setting the compared bth bits to zero before storage. In general, since accumulated transition probabilities are monotonically increasing for transition probabilities of paths through the trellis in both forward and reverse directions, the present invention may be employed for both threshold normalization of both the forward (&agr;) and reverse (&bgr;) transition probabilities.

Abstract: An iterative decoder limits the range of extrinsic information used for iterative decoding of an encoded frame of data. The iterative decoder includes two or more separate decoders for decoding a received encoded frame of data. Each decoder employs extrinsic information generated from the soft data generated by another decoder decoding the encoded frame of data. The extrinsic information includes an approximate measure of the probability that a particular transmitted bit received by the iterative decoder is a logic 0 or logic 1. The extrinsic information for the bit originates with one decoder and is used by another decoder as external information about that bit. Implementations of the iterative decoder use saturation values to define the boundaries of the range. The saturation values are selected such that either no or relatively small degradation in BER occurs, and the saturation values also define the width of the binary representation of the extrinsic information.

Abstract: A set of orthogonal sequences (e.g., Hadamard sequences) is decomposed into a set of basis vectors and sets of coefficients, where each set of coefficients represents a particular “vector combination” of the basis vectors that forms one of the orthogonal sequences. Such decomposition of orthogonal sequences into basis vectors and sets of coefficients may allow for a reduction in memory space and/or processing required to generate one or more of the orthogonal sequences during real-time operations of a communications system, such as an IS-95 CDMA system, that employs the orthogonal sequences. In one embodiment, a Hadamard sequence generator includes a controller, a memory, and a combiner. The set of basis vectors are stored in the memory, and each of the Hadamard sequences has a corresponding set of coefficients from which the Hadamard sequence can be derived as a vector combination of the basis vectors.

Abstract: A method and apparatus are disclosed for determining the data rate of a received signal in a communication system utilizing code division multiple access (CDMA) techniques. The well-known Viterbi decoding-based rate detection approach is combined with the conventional repetition pattern-based rate detection approach. The hybrid approach possesses the advantages of both prior approaches, without their disadvantages. The computationally efficient repetition pattern-based data rate detection approach, while not as reliable as the Viterbi decoder-based data rate detection approach, provides reliable data rate detection most of the time. The repetition-pattern data rate detection approach is used as long as a predefined reliability metric is satisfied, and only uses the more computationally intensive Viterbi decoder-based data rate detection approach when detection reliability may be compromised.

Abstract: An offset sequence generator generates an offset sequence from a reference sequence, the offset sequence being a cyclic-shifted version of the reference sequence. The reference sequence is a deBruijn sequence formed from a pseudo-noise (PN) sequence augmented with an insert-bit, the insert-bit being inserted at a rollover state of the PN sequence. The offset generator includes a decision circuit that selects values of either the reference sequence or a delayed reference sequence as an input to a mask circuit. The mask circuit applies masks so as to generate the PN sequence of the offset sequence. The decision circuit also detects the rollover state of the PN sequence of the offset sequence, and inserts the insert-bit so as to provide the offset sequence.
