摘要： Techniques to acquire pilots over code space and/or frequency errors. In one aspect, pilot acquisition is performed using a number of substages, and some of the substages are pipelined and performed in parallel using different processing elements. A searcher initially searches over a designated code space to find peaks, and these peaks may be re-evaluated. Finger processors then attempt to acquire the candidate peaks. The searcher may be operated to search for the next set of peaks while the finger processors process the current set of peaks. In another aspect, the full range of frequency errors for the pilots is divided into a number of frequency bins. A multi-stage scheme is used to evaluate the bins, and may employ pipelining and parallel processing such that a search for peaks in the next bin is performed while acquisition of peaks found for the current bin is attempted.

摘要： A system and method for adjusting loop bandwidth in a synchronization loop of a radio receiver uses a noncoherent peak detector (102) to determine the maximum magnitude and timing of incoming data at various code phase offsets. The maximum magnitude and timing are used in subsequent processing with the maximum magnitude value used to determine an adjustment factor. The timing information associated with the maximum signal value is used to despread the incoming signal. The despread incoming signal is subsequently scaled in accordance with the determined adjustment factor such that the input to the synchronization loop is scaled to produce the desired loop bandwidth.

摘要： Techniques to search for pilots over code space in a CDMA system where two substages are used to search for pilots. The detect substage searches through (e.g., fixed-size) search windows to detect for peaks in the received signal. The "dwell substage" then searches through (e.g., variable-size) search windows to re-evaluate the detected peaks and remove noise peaks. The dwell windows may be formed using a combination of overlapping search windows, such that a code space as small as possible is searched (to reduce search time) but large enough to account for possible drift in the detected peaks. Variable number of peaks may be provided by the dwell substage for the variable-size dwell windows.

摘要： For frequency bin error estimation, multiple hypotheses are formed for different frequency bin errors, pilot offsets, or combinations of frequency bin error and pilot offset. For each hypothesis, received symbols are extracted from the proper subbands determined by the hypothesis. In one scheme, the extracted received symbols for each hypothesis are despread with a scrambling sequence to obtain despread symbols for that hypothesis. A metric is derived for each hypothesis based on the despread symbols, e.g., by deriving a channel impulse response estimate based on the despread symbols and then deriving the metric based on the channel impulse response estimate. In another scheme, the extracted received symbols for each hypothesis are correlated, and a metric is derived based on the correlation results. For both schemes, the frequency bin error and/or the pilot offset are determined based on the metrics for all hypotheses evaluated.

摘要： Techniques for performing time tracking at a receiver are described. A first arriving path (FAP) and a last arriving path (LAP) are detected based on a channel impulse response estimate for a communication channel. The detected FAP and LAP may be correct or swapped. To resolve ambiguity in the detected FAP and LAP, a first hypothesis corresponding to the FAP and LAP being correctly detected and a second hypothesis corresponding to the FAP and LAP being incorrectly detected are evaluated. For each hypothesis, hypothesized FAP and LAP are determined based on the detected FAP and LAP, a correlation window is determined based on the hypothesized FAP and LAP, and correlation is performed using the correlation window. The correct hypothesis is determined based on correlation results for the two hypotheses. The receiver timing is updated based on the hypothesized FAP and LAP for the correct hypothesis and used for demodulation.

摘要： Techniques for operating two receivers to receive data and paging from two systems are described. A primary receiver is associated with better performance than a secondary receiver under poor RF conditions. The two receivers may be operated in either a hybrid mode in which the primary receiver is used to receive paging or a simultaneous mode in which the second receiver is used to receive paging. One of the modes may be selected for use based on RF conditions, received power, demodulation metrics, and/or other criteria. In one design, a mode is selected based on the received power and one or more thresholds. In another design, the hybrid mode is selected for poor RF conditions and, for good RF conditions, the hybrid or simultaneous mode is selected based on received power.
