Abstract: Apparatus and methods for use in a wireless communication system are disclosed for determining a timing position for channel activity in order to resolve timing ambiguity. A disclosed apparatus includes a processor that determines when channel activity occurs in at least one of an early or a late arrival position in a communication channel estimate and unwraps the channel activity in either the early arrival position or the late arrival position to a corresponding late or early arrival unwrapped channel activity position in the wireless channel estimate. The processor correlates symbol data in the communication signal corresponding to both the channel activity and the unwrapped channel activity to symbol data of the main channel activity. The processor determines whether a correct timing position of the channel activity is one of the early or late arrival positions based on the correlations, thus resolving timing ambiguity. Complementary methods are also disclosed.

Abstract: Apparatus and methods for use in a wireless communication system are disclosed for recovery of timing tracking in a device, such as a wireless transceiver, after decoding errors occur due to incorrect timing tracking. In particular, the disclosed methods and apparatus recover timing tracking by monitoring a decoded signal in the transceiver for decoding errors occurring during a first frame, determining whether a number of decoding errors is greater than a predetermined amount, reacquiring a first pilot channel at a start of a subsequently received second frame when the number of decoding errors is determined to be greater than the predetermined amount, and resetting timing tracking of the transceiver based on the reacquired first pilot channel.

Abstract: Apparatus and methods for estimating the frequency of a sleep or slow clock using a fast clock, such as a temperature compensated crystal oscillator. The disclosed apparatus include an estimator having a first counter that receives sleep clock synchronized pulses issuing each cycle of the sleep clock period, yet are synchronized to a fast clock. The slow clock synchronized pulses are counted up to a predetermined number; whereupon a full count signal is issued. A second counter receives the full count signal and increments each time the full count signal is received. A third counter counts fast clock cycles until the full count signal occurs. Based on the number of counts of the slow and fast clock cycles, the frequency of the slow clock may be determined using only the domain of the fast clock for performing the measurement thereby tying accuracy of the measurement to the accuracy of the fast clock.

Abstract: A system and method for providing an alternate keypad arrangement in a virtual keypad is presented. In the alternate keypad arrangement, the virtual keys are laid out in a non-sequential arrangement. In one embodiment, the labels displayed on the virtual keys appear sequential, however the values registered when the user presses the virtual key does not match the label and, hence, the values are laid out in a non-sequential manner. Using alternate keypad arrangements arranged in patterns enables the user to use a common pattern, or patterns easily remembered by the user, for a wide variety of authentication data used to access a wide variety of systems. Rather than remembering the specific PIN codes and passwords, the user simply remembers a pattern and selects virtual keys that match the pattern.

Abstract: Method and apparatus for transmitting a wireless communication signal frame, such as an OFDM superframe. In particular, the disclosed methods and apparatus transmit a first pilot symbol in the signal frame where the symbol serves to communicate coarse timing information to a receiver. A second pilot symbol is subsequently transmitted to communicate information including network identification information concerning a wide-area network. Next, overhead information (OIS) concerning the wide-area network is then transmitted and then a third pilot symbol is transmitted to communicate information including network identification information concerning a local-area network to a receiver. By transmitting the third pilot symbol concerning the local-area network after the wide-area OIS, a receiver is allowed to acquire wide-area network timing and information and then subsequently acquire more updated local-area network timing and information and more efficiently utilize processing resources.

In particular, the methods and apparatus generate at least one pseudo-random noise sequence having at least a predetermined length, where the at least one pseudo-random noise sequence represents a system configuration of a wireless system. A time domain symbol sequence is modulated with the at least one pseudo-random noise sequence to create a timing acquisition pilot symbol. The modulated acquisition pilot symbol is further masked to a prescribed frequency profile and placed in a frame for wireless transmission.
