    摘要： Disclosed are various embodiments involving a two-step searcher for cell discovery. Multiple scrambling codes associated with multiple neighboring cells are obtained. Slot timing is obtained for a received signal based at least in part on a detection of primary synchronization peak energy in the received signal. One of the scrambling codes for decoding the received signal is identified based at least in part on testing multiple scrambling code hypotheses in parallel during an accumulation time period of the received signal in response to obtaining the slot timing.

    摘要： A method and system for decoding control data in GSM-based systems using inherent redundancy and physical constraints are presented. At least one estimated GSM-based bit sequence may be selected by performing searches that start from trellis junctions determined by the decoding algorithm. The estimated bit sequences may be selected based on corresponding redundancy verification parameters. At least one physical constraint test may be performed on the selected estimated GSM-based bit sequences to select a decoded output GSM-based bit sequence. A multilayer decoding process may comprise a burst process and a frame process. Results from a first burst process may be utilized to generate a decoded GSM bit sequence in the frame process. The frame process may utilize redundancy information and physical constraints to improve the performance of a decoding algorithm.

    摘要： Methods and systems for processing audio signals are disclosed herein. Aspects of the method may comprise controlling gain during multipath, multi-rate audio processing by generating a digital signal that is a product of an input digital signal and a gain coefficient derived from a lookup table, and coarse tuning the gain by bit-shifting the digital signal to generate a digital output signal. The gain may be fine-tuned utilizing a variable step size determined by interpolation. The gain coefficient may be partitioned into gain blocks, which may be twice a corresponding value in preceding gain blocks. The gain blocks may be partitioned into steps that represent particular gain values within a range associated with the gain block. The digital output signal may be ramped utilizing a linear interpolation of the gain coefficients over a number of samples of the input signal, where the number of samples is given as a power of two.

    摘要： Various aspects of a method and system for adaptive multi rate and measurements adaptation may include a processor that enables computation of at least one signal level measurement for at least one received signal. The processor may enable cancelling of interfering signals received in addition to the received signal based on processing of a received bit sequence using a first burst process operation (BP) in a first decoding algorithm that utilizes SAIC operations. The processor may also enable cancelling of noise signals received in addition to the received signal based on processing the received bit sequence using a second BP operation that utilizes redundancy and imposes a physical constraint during decoding. The processor may also enable adjustment of the computed at least one signal level measurement.
