Abstract: Techniques are described herein that perform symbol-level equalization using multiple spreading factors. The techniques may allow for symbol-level equalization to be performed between a serving cell and a non-serving cell(s) for WCDMA and HSDPA protocols, for example. A serving cell operates using a first spreading factor, and a non-serving cell(s) operates using a second, different spreading factor. Data communications received from the serving cell and the non-serving cell(s) may be aligned using extended channel representation(s) of the non-serving cell(s) and/or scrambling code offset(s). The aligned communications may be equalized using symbol-level equalization to obtain a joint linear minimum mean square error between the serving cell and the non-serving cell(s).

Abstract: One or more aspects of the disclosure provide an efficient equalization scheme capable of mitigating multi-path interference on channels with large delay spread using short-length equalizers. That is, by dividing stored samples of a signal received on the multi-path channel by time into a plurality of clusters, a short-length equalizer can be utilized in an iterative fashion on each of the clusters, thus eliminating the need for a large length equalizer while still providing improved performance over that of a Rake receiver at large delay spreads. Other aspects, embodiments, and features are also claimed and described.

Abstract: A wireless terminal is operable to receive a Wideband Code Division Multiple Access (WCDMA) signal from a base station and includes clock circuitry, a wireless interface, and a Primary Synchronization (PSYNC) module (708). The clock circuitry generates a wireless terminal clock using a wireless terminal oscillator. The wireless interface receives the WCDMA signal, which is produced by the base station using a base station clock that is produced using a base station oscillator that is more accurate than the wireless terminal oscillator. The PSYNC module includes a plurality of PSYNC correlation branches (808A-808N). Each PSYNC correlation branch phase rotates the WCDMA signal based upon a respective frequency offset (806), correlates the phase rotated WCDMA signal with a Primary Synchronization Channel (PSCH) code over a plurality of sampling positions (808), and produces PSYNC correlation energies based upon the correlations for each of the plurality of sampling positions (810).

Abstract: In High-Speed Downlink Packet Access (HSDPA) communications in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system (called TD-HSDPA), the payload of two High-Speed Shared Information Channels (HS-SICHs) may be bundled into one HS-SICH channel by reusing the unused uplink synchronization shift (SS) for power control purposes. Thus, the HS-SICH spreading factor (SF) 16 code channel overhead may be reduced by 50%.
