FHSS Perforn"lance Considerations
Typically, a large number of frequencies are used in FHSS so that Ws i~ much larger
than Wd• One benefit of this is that a large value of k results in a systen, that is quite
resistant to noise and jamming. For example, suppose we have an MFSJ Ctransmitter
with bandwidth Wd and noise jammer of the same bandwidth and fixe< l power Sj on
the signal carrier frequency. Then we have a ratio of signal energy pe r bit to noise
power density per Hertz of
