    • A mobile device comprises multiple receive antennas to receive spatially independent multipath signals from multiple transmit antennas located on a single base station. The mobile device concurrently generates a RAKE-based equivalent single path signal (RAKE ESPS) and an equalizer-based equivalent single path signal (equalizer ESPS) for the multipath signals received via each receive antenna. The generated RAKE ESPS or the generated equalizer ESPS is selected for channel decoding. Reference signal components are extracted from the multipath signals received to determine noise components, which is used to determine signal quality information of the generated RAKE ESPS and the generated equalizer ESPS. A final ESPS is selected from the generated RAKE ESPS and the generated equalizer ESPS based on the corresponding determined signal quality information. The selected final ESPS is diversity processed by combining signal components over the transmit/receive antennas. Transmission parameters are determined for channel decoding the combined signals.
    • 移动设备包括多个接收天线以从位于单个基站上的多个发射天线接收空间上独立的多径信号。 移动设备同时产生用于经由每个接收天线接收的多径信号的基于RAKE的等效单路径信号(RAKE ESPS)和基于均衡器的等效单路径信号(均衡器ESPS)。 选择生成的RAKE ESPS或生成的均衡器ESPS进行信道解码。 从所接收的多径信号中提取参考信号分量以确定噪声分量,其用于确定所生成的RAKE ESPS和生成的均衡器ESPS的信号质量信息。 基于相应确定的信号质量信息,从生成的RAKE ESPS和生成的均衡器ESPS中选择最终ESPS。 所选择的最终ESPS通过在发射/接收天线上组合信号分量进行分集处理。 确定传输参数用于信道解码组合信号。
