摘要： A UE receives HSDPA traffic comprising legacy HSDPA traffic and HS-SCCH-less HSDPA traffic. The UE concurrently processes the received legacy HSDPA traffic and the received HS-SCCH-less HSDPA traffic. The received HSDPA traffic is concurrently buffered into a first storage and a second storage to support simultaneously receiving legacy HSDPA traffic and HS-SCCH-less HSDPA traffic. A HARQ process is performed on the buffered HSDPA traffic in the first storage or the second storage according to a corresponding HS-SCCH CRC test. The resulting HARQ processed HSDPA traffic is Turbo decoded. Turbo decoding on the previously HARQ processed HSDPA traffic is performed simultaneously with HARQ processing on the buffered HSDPA traffic in the first storage or the second storage. The buffered HS-SCCH-less HSDPA traffic is processed via HARQ processing and Turbo decoding for each of the four pre-determined transport formats.

摘要： A UE in an URA_PCH state or a Cell_PCH state receives a HS-PDSCH without an associated HS-SCCH. No dedicated H-RNTI is assigned to the UE. The received HS-PDSCH is separately processed using one or more different predetermined transport format. The different predetermined transport formats are identified from associated HS-DSCH paging system information block. The UE starts blindly processing the received HS-PDSCH by determining a set of configuration parameters according to a first transport format of the identified predetermined transport formats. One or more associated device components such as hardware components of the UE are configured using the determined set of configuration parameters. The configured device components are used to perform HARQ processing, IR combining and/or Turbo decoding on the received HS_PDSCH without associated HS_SCCH. The UE continuously processes the received HS-PDSCH using the next available predetermined transport format when a CRC test completes with an error.

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： A wireless terminal is operable to receive a Wideband Code Division Multiple Access (WCDMA) signal from a base station and includes clock circuitry, a wireless interface, and a Primary Synchronization (PSYNC) module. The clock circuitry generates a wireless terminal clock using a wireless terminal oscillator. The wireless interface receives the WCDMA signal, which is produced by the base station using a base station clock that is produced using a base station oscillator that is more accurate than the wireless terminal oscillator. The PSYNC module includes a plurality of PSYNC correlation branches. Each PSYNC correlation branch phase rotates the WCDMA signal based upon a respective frequency offset, correlates the phase rotated WCDMA signal with a Primary Synchronization Channel (PSCH) code over a plurality of sampling positions, and produces PSYNC correlation energies based upon the correlations for each of the plurality of sampling positions.
