摘要
Most modulated signals are cyclostationary, which results in redundancy in the signal frequency spectrum. In this paper, the spectral redundancy which exists in Code Division Multiple Access (CDMA) signals is used in the receiver to improve performance. In particular, we employ a Frequency Shift-Decision Feedback Equalizer (FRESH-DFE) to exploit the cyclostationary. We show that FRESH-DFE is superior to conventional DFE in multiple access CDMA systems, including long code systems.
