In this paper, we propose a new linear detector for the iterative receiver for MIMO-BICM systems. Instead of performing vector matched filtering after the interference cancellation, the proposed detector successively combines the soft information from different receive antennas, where the combining factors are computed based on the joint likelihood function of multivariate Gaussian random variables. Numerical results show that significant performance improvement can be achieved and the additional complexity is negligible.
