Prior to developing BER results for BPSK in Rician fading, it is worthwhile
investigating the characteristics of the Rician channel using the simple model
in Figure 6.6 where the BPSK modulator is fed with random integers. In this
model, the box for selection of Rician fading channel parameters is checked
to open the channel visualization at the start of the simulation. In this simulation,
specific parameters include the Rician K factor that specifies the ratio
of the specular component to the diffuse multipath components, the Doppler
shift associated with the specular (line-of-sight) component, and the maximum
Doppler shift associated with the diffuse multipath components. This
