Abstract:
1. A method of Interference Signal Code Power (ISCP) measurement, in a Time-Division, Synchronous Code-Division Multiple Access (TD-SCDMA) communication system utilizing channel estimation processes, wherein a plurality of coded signals are transmitted from individual remote units that are distinguished by specific encodings, and wherein the specific encodings comprises a midamble divided into a plurality of channel windows having a pluality of channel windows responses, the method comprising: extracting the midamble; estimating the channel window responses based at least in part on the midamble; forming channel window response vectors based at leat in part on the channel window responses; calculating powers of the channel windows using the channel window response vectors; comparing and sorting the powers of the channel windows; forming a low-power vector utilizing a number of the channel window response vectors with the lowest powers; and utilizing the low-power vector in the computations of the ISCP.
