Abstract: Optimal circular buffer rate matching for turbo code. An offset index, ?, of 3 and a skipping index, ?, of 3 is employed in accordance with circular buffer rate matching. This allows less puncturing of information bits and more puncturing of redundancy/parity bits (e.g., which can provide for a higher rate). Multiple turbo codes may be generated from a mother code such that each generated turbo code can be employed to encode information bits. For example, a first turbo coded signal can be generated using a first turbo code generated from the mother code, and a second turbo coded signal can be generated using a second turbo code generated from the mother code. Any of these turbo coded signal can be decoded using parallel decoding processing or a single turbo decoder (when each turbo coded signal undergoes processing to transform it back to the mother code format).

Abstract: Aspects of a method and system for extending dynamic range of an RF signal are provided. In this regard, an amplitude signal that is representative of an amplitude of a pair of baseband signals may be generated, an amplitude of the generated amplitude signal may be modified according to a function; and an amplitude of the baseband signals may be modified according to an inverse of the function. The modifications may adjust the peak-amplitude-to-average-amplitude ratio of one or more signals. An intermediate signal may be generated from the modified baseband signals and the amplitude of the intermediate signal may be amplitude modulated by the intermediate signal. The intermediate signal may be amplitude modulated by controlling a gain of a power amplifier. The intermediate signal may be amplitude modulated by controlling a current source and/or voltage source supplying power to a power amplifier.

Abstract: Adaptive interference cancellation algorithm using speech mode dependent thresholds. A method of processing radio frequency (RF) bursts dependent on a speech mode associated with data contained within the RF burst is presented. Different voice modes, full rate, half rate, and adaptive multi-channel rates each may require different signal to noise ratio (SNR) conditions in order to be successfully processed. To improve the equalization, the SNR associated with the burst is estimated. Based on the SNR or other related conditions, a decision can be made as to whether or not an interference cancellation burst process should be implemented. For example, any one or more of SNR of the signal, a measure of colored noise within the signal, an indication whether the signal being noise limited or interference limited, and a channel profile of the signal may indicate the presence of interference requiring the cancellation of such interference.

Abstract: Turbo coding having combined turbo de-padding and rate matching de-padding. An approach is presented by which a singular module is operable to perform both zero bit de-padding and dummy bit de-padding in accordance with turbo encoding. Zero padding can be performed on an input information stream before undergoing turbo encoding. One or more of the 3 outputs from the turbo encoding module (e.g., systematic bits, parity 1 bits, and parity 2 bits) may then undergo dummy bit padding as well. Thereafter, these 3 streams (some or all of which may have undergone dummy bit padding) undergo sub-block interleaving. After all of these operations have taken place, a singular combined de-padding module that can be employed to perform de-padding any zero padded bits and any dummy padded bits from each of the three streams that have undergone the sub-block interleaving.

Abstract: Systems and methods are disclosed for detecting temporary high level impairments, such as noise or interference, for example, in a communications channel, and subsequently, mitigating the deleterious effects of the dynamic impairments. In one embodiment, the method not only performs dynamic characterization of channel fidelity against impairments, but also uses this dynamic characterization of the channel fidelity to adapt the receiver processing and to affect an improvement in the performance of the receiver. For example, in this embodiment, the method increases the accuracy of the estimation of the transmitted information, or similarly, increases the probability of making the correct estimates of the transmitted information, even in the presence of temporary severe levels of impairment. The channel fidelity history may also be stored and catalogued for use in, for example, future optimization of the transmit waveform.
