SYMBOL-LEVEL EQUALIZATION USING MULTIPLE SPREADING FACTORS

摘要

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).

1. A method, comprising:
receiving first data communications from a serving cell that operates using a first spreading factor; receiving second data communications from at least one non-serving cell that operates using a second spreading factor that is different from the first spreading factor; and performing symbol-level equalization on a first plurality of data communications that includes the first data communications and the second data communications.
