BER eventually converges to a max. So, for simplicity reasons the detector in this paper only

uses one iteration.

Figure 10 - Iterative Detector Model in SESS

3.6 Iterative Detector Performance

The performance of the iterative detector can be seen in Figure 11 and Figure 12 on the

next page. Figure 11 shows that the detector in an AWGN channel performs at a BER of 10-4

nets a 3 db gain over the BPSK system. The real surprise comes from the performance in a

Rayleigh fading channel, in Figure 12. It shows that at a lower 10-3 BER, the detector is able to

improve by over the BPSK system by about 15db. In fact, it is almost able to achieve the
