he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a constant period. The current value of this signal at a certain poiTnt of time is proportional to its Duty Cycle. That s the High Time during one perio ...

We simulate uncoded BER of BPSK modulated
data as a function of SNR
-in an AWGN channel
-in a Rayleigh fading channel
-in an AWGN channel when direct sequence spreading
is used
and compare results to the theoretical ones.
We assume coherent receiver and perfect
synchronization.
