Turbo diversity based on SC/MMSE equalization

In this paper, an iterative (turbo) technique, soft-cancellation followed by minimum mean squared error filtering (SC/MMSE), is applied to the diversity combining of broadband single-carrier signals using multiple antennas. The major aim of this approach is to reduce the computational complexity of the original SC/MMSE equalization algorithm. It is shown that the performance of the proposed turbo diversity technique can asymptotically achieve that of the original SC/MMSE equalizer.
