Abstract:
A method to process DP bits and TPC bits from multiple fingers within a WCDMA rake receiver is provided. DPCH symbols are received, quantized and channel compensated. Then processing operations for individual fingers for the channel compensated quantized despread DPCH symbols containing DP bits and TPC bits are chosen based on the DPCH slot format. The DPCH symbols are processed based on the DPCH slot format in order to produce processed DPCH pilot symbols in a common format. DP bits and TPC bits may be processed in parallel by separate processing branches or in series by applying timing control to common processing modules. These processed symbols may then be combined. Other embodiments may further allow for the computation of an SNR estimate based on the combined DPCH symbols.
