A Two-Stage Decision-Directed Receiver for CDMA MIMO Systems over Multipath Fading Channel

摘要

In this paper, a low-complexity two-stage decision-directed receiver is proposed for a code-division multiple access (CDMA) multiple-input multiple-output (MIMO) system using space-time block coding (STBC) over a multipath fading channel. In contract to the conventional receivers, the proposed blind receiver can provide a reliable performance without requirement of the pilot symbols.
