# 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.

# Figure 7 – SESS Performance in Rayleigh Fading Channel

# 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.
