Doubly Iterative Soft Interference Cancellation for MIMO-OFDM Systems
In this paper, we consider a coded OFDM system in MIMO wireless fading channels, where the transmitter as well as the receiver is equipped with multiple antennas. The serial binary information bits are first partitioned into groups, and then individually encoded, bit interleaved, OFDM modulated, and transmitted through its transmit antenna. At the receiver, we investigate a reduced complexity doubly iterative soft interference canceller (SIC) structure based on the minimum mean square error (MMSE) criterion (originally proposed in a BPSK context) to this particular scheme. For systems with both iterative SIC and a priori information in the symbol demapper, i.e. doubly iterative, the receiver performance is proved to be greatly improved.
