Abstract :
We analyze and compare the performance of two kinds of MMSE receivers for asynchronous CDMA channels, which are termed chip-MMSE receiver and multi-shot bit-MMSE receiver respectively. Comparative results show that chip-MMSE receiver provides considerably better performance than multi-shot bit-MMSE receiver in asynchronous CDMA channels, more so as the power of interferer users increases
