accumulate in the receiver registers that exceed N/2. So, as N→∞ the probability for error
approaches that of a BPSK system which is confirmed in Figure 6 on page 18 and with Equation
(8 on the previous page.
The SESS system behaves similarly in a Rayleigh Fading channel as the AWGN channel
as seen in Figure 6 below.

Observe how when N gets bigger, the simulation converges toward the theoretical
Rayleigh Fading Channel line. This is the same behavior as is see in the AWGN channel, in that,
as N→∞ the probability of error approaches that of a BPSK system in that channel.
