Abstract

The large area synchronized (LAS) smart spreading codes having an interference free window (IFW), makes high-dimension modulation patterns be feasible in CDMA system. Combining MIMO with LAS codes can effectively take advantage of multipath delay spread and the random fading characteristic of the mobile propagation channel. In this paper, we show that by using the turbo product codes (TPC) to utilize soft-in-soft-out (SISO) iterative multi-user detection algorithm in such a system, significant performance improvement, and high spectrum efficiency could be achieved.
