摘要： An initialization method is performed to initialize the states for producing downlink scrambling code for a wideband code division multiple access (WCDMA) mobile device. The initialization method uses an auxiliary linear feedback shift register (x-LFSR) advance the x-initial state to a new initial state that corresponds to a selected downlink scrambling code. The new initial state allows the remaining masks used for generating the downlink scrambling code to be fixed. Memory required to produce the downlink scrambling codes is therefore reduced, as it is no longer dedicated to storing the sets of masks corresponding to each of the possible downlink scrambling codes.

摘要： A pipelined cell search apparatus having a primary search stage, a secondary stage and a Gold code stage. The primary stage receives a primary synchronization channel (P-SCH) signal, detects a maximum peak of a slot boundary in the P-SCH signal, and generates slot timing data from the maximum peak. The secondary search stage receives a secondary synchronization channel (S-SCH) signal and the slot timing data, and detects in the S-SCH signal a maximum peak of a frame boundary. The secondary search stage generates frame timing data and a group ID of a base station transmitting the P-SCH signal and the S-SCH signal. The Gold code search stage receives a common control pilot channel (CPICH) signal, the slot timing data, the frame timing data, and the group ID and detects in the CPICH signal a maximum peak associated with a Gold code of the base station.

摘要： A signal-to-noise estimator is provided for estimating the signal-to-noise ratio in wireless fading channels. The estimator can be applied to likelihood ratio estimation of turbo decoders in third generation wide-band code division multiple access (WCDMA) systems. Time-multiplexed samples of pilot symbols from a wireless receiver are supplied to the estimator to obtain individual estimates of signal power and/or noise power. The estimator uses a de-correlating filter in which the coefficients are known functions (such as eigen-vectors) of the auto-correlation matrix for a wireless channel. The decorrelating filter is used by the estimator to map an observation vector into a set of statistically independent samples. The energy of each vector component is computed individually and combined to produce an aggregate sum for the vector. The aggregate sum can be subtracted from the pilot tone power in order to produce an estimate of noise power.
