摘要： In a WCDMA network, a communication system may include a baseband processor that enables determination of a primary synchronization position and a plurality of scrambling codes based on received configuration information from at least one base station. The baseband processor may also determine a slot boundary in at least one signal received from the at least one base station based on the determined primary synchronization position. The baseband processor may concurrently apply segments of the plurality of scrambling codes to the received at least one signal. The segments of the plurality of scrambling codes are generated from a plurality of time shifted versions of one of the plurality of scrambling codes. The system may also include a multipath detector that enables unscrambling of the received at least one signal based on the determined slot boundary and at least a portion of the one or more scrambling codes.

摘要： Methods and systems for dual frequency timing acquisition for compressed WCDMA communication networks may include processing received WCDMA signals. The WCDMA signals, which may be primary synchronization channel signals, may comprise signals transmitted by one base station at one frequency band and by another base station at a different frequency band, during a compressed frame. Samples of the received WCDMA signals from the different base stations may be stored in portions of a memory allocated for signals from each base station. The received WCDMA signals having the first frequency band may be processed via the processing circuitry during a non-compressed frame. The samples corresponding to the signals with the first frequency band during the non-compressed frame may be stored in the memory.

摘要： Estimating error signals in a communication system may include determining a frequency error of a received RF signal utilizing a plurality of correlators, where one or more of the correlators may be fed with a carrier frequency of the received RF signal and a remaining portion of the plurality of correlators may be fed with one or more other carrier frequency. This carrier frequency fed to the remaining portion of the plurality of correlators may differ from the carrier frequency of the received RF signal. The received RF signal may comprise a primary synchronization channel (PSC) code for wideband code division multiple access (WCDMA). The carrier frequency of the received RF signal may be rotated in an I and Q coordinate system so as to generate the other carrier frequency.

摘要： Aspects of a method and apparatus for user equipment (UE) channel acquisition in the presence of large frequency uncertainty in wideband code division multiple access (WCDMA) signals are provided. An efficient time-frequency domain search that may be utilized in cell communications may be performed by devising criteria that eliminates the unlikely frequencies hypotheses. An estimate for the frequency offset may be estimated in the remaining subset. For WCDMA applications, a UE may comprise a baseband processor that is enabled to detect a primary synchronization channel (P-SCH) code (PSC) for initial network synchronization. A portion of the baseband processor may generate a plurality of signal peak-to-noise-floor-average ratios associated with a plurality of test frequencies produced by a crystal oscillator. A highest of the signal peak-to-noise-floor-average ratios may be selected to determine the frequency offset of the crystal oscillator for use in power up operations

摘要： A mobile device receives a signal, from a base station, comprising a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). The mobile device utilizes two different sampling rates to perform the PSS synchronization and the SSS detection individually. For example, the mobile device synchronizes to the received PSS at a first sampling rate such as 0.96 MHz, which is determined based on the PSS transmission rate and/or the length of the received PSS. The mobile device detects the received SSS at a second sampling rate such as 1.92 MHz, which equals to the sampling rate for an analog-to-digital conversion at the mobile device. The received PSS and associated symbol timing are detected through the PSS synchronization to support the SSS detection. The detected SSS is used to acquire cell-specific parameters such as cell ID. The acquired cell-specific parameters ensure proper communications between the mobile device and the base station.
