Turbo coded MIMO multiplexing with iterative adaptive soft parallel interference cancellation
説明
An iterative adaptive soft parallel interference canceller (ASPIC) is proposed for turbo coded multiple-input multiple-output (MIMO) multiplexing. ASPIC is applied to transform a MIMO channel into single-input multiple-output (SIMO) channels for maximum ratio diversity combining (MRC). In the iterative ASPIC, replicas of the interference from different transmit antennas are generated and subtracted from the received signals. The log-likelihood ratio (LLR) sequence, obtained as the turbo decoder output, is fed back for iterative interference cancellation. At the transmitter, the information bit sequences and parity bit sequences are transmitted from different antennas. The achievable bit error rate (BER) performance of turbo coded MIMO multiplexing with the proposed iterative ASPIC in a Rayleigh fading channel is evaluated by computer simulation.
