EN In this paper, a transmission scheme with iterative processing of received signals is proposed for Wireless Local Area Networks (WLANs) employing spatial multiplexing. The scheme consists in applying channel coding, interleaving and iterative detection and decoding (IDD) separately for a tuple of OFDM symbols (hereinafter called an OFDM multi-symbol), transmitted simultaneously in the same signaling interval via different space streams. In a conventional approach to iterative decoding, high receiver latency occurs because of the need to wait until the whole (possibly very large) data frame has been acquired by the receiver prior to the start of any decoding. In the proposed solution, the latency is limited to single OFDM symbol interval. This is a great advantage when iterative decoding is used.
