摘要：
We propose a coding strategy for MIMO OFDM systems that exploits full spatial (transmit and receive) diversity, as well as frequency and time diversity, through the combination of binary codes and linear precoding. The proposed scheme, based on streams (layers/threads), was designed to make iterative decoding with interference-cancellation relatively simple, while preserving most of the diversity available from the channel. It accommodates any number of transmit and receive antennas. Nevertheless, it is a full-rate scheme, since no redundancy is added by the linear precoding operations.
