摘要： A system for processing radio frequency (RF) signals includes a searcher and a plurality of Cluster Path Processor (CPPs). The searcher detects a maximum signal energy level and position of at least one of a plurality of individual distinct path signals in a signal cluster of a first information signal, wherein at least a portion of the plurality of individual distinct path signals is received within a duration of a corresponding delay spread. The sampling position is used as a starting sampling location by the plurality of CPPs, including a first information signal CPP and a second information signal CPP. Fine sampling positions of the plurality of CPPs are based upon channel energy estimates for the plurality of individual distinct path signals. CPP outputs are employed to produce channel estimates, which are themselves used in subsequent equalization operations. Sampling positions may change over time in order to satisfy alignment criteria.

摘要： A baseband processing module includes TX processing components, a processor, memory, an RX interface, and a cell searcher module. The TX processing components receive outbound data, process the outbound data to produce a baseband TX signal, and output the baseband TX signal to a RF front end of the RF transceiver. The RX interface receives a baseband RX signal from the RF front end carrying a WCDMA signal. The cell searcher module receives the baseband RX signal, scans for WCDMA energy within the baseband RX signal, acquires slot synchronization to the WCDMA signal based upon correlation with a Primary Synchronization Channel (PSCH) of the WCDMA signal, acquires frame synchronization to, and identify a code group of, the WCDMA signal based upon correlation with a Secondary Synchronization Channel (SSCH) of the WCDMA signal, and identifies the scrambling code of the WCDMA signal based upon correlation with a Common Pilot Channel (CPICH) of the WCDMA signal.

摘要： RF communications received by a wireless terminal from a servicing base station are used to determine the channel quality such as reported bit error probability (BEP). The RF communications may be in the form of RF bursts that are part of a data frame. An estimated BEP may be determined from the signal to noise ratio (SNR) of the RF bursts and or a sequence of soft decisions extracted from the RF bursts, and their historical performance. The SNR maps to an estimated BEP based upon the modulation format of the RF bursts. The soft decisions decode to produce a data block. When the soft decisions decoded favorably, the re-encoded data block produces a sequence of re-encoded decisions. Comparing the re-encoded decisions to the soft decisions yields a re-encoded bit error (RBER). The reported BEP may be based upon the estimated BEP, RBER, and/or RBER threshold. The RBER threshold may be adaptively incremented or decremented depending upon whether or not the RF communications were properly decoded. The size of the increment or decrement may be based on the channel quality.
