Zusammenfassung:Methods and apparatus are disclosed for improving the frame error rate performance of a multi-input multi-output orthogonal frequency division modulation (MIMO-OFDM) system with a limited-bandwidth feedback channel is disclosed. Successive interference cancellation (SIC) is used to improve MIMO-OFDM system performance gain with cyclic redundancy check (CRC) and convolutional codes (CC). Additional performance gains are obtained when MIMO channel state information (CSI) is available at the transmitting unit.
