Abstract:

The performance of cascaded binary communication links in the presence of additive white gaussian noise is investigated for the cases of constant and Rayleigh distributed signal levels. An exact expression is derived for over-all error probability for any number of links with constant signal levels. With Rayleigh fading, the cases of independent and completely correlated fading are considered. An exact expression is derived for average over-all error probability for any number of links with independent Rayleigh fading and identical average signal-to-noise ratios in each link. A simple approximation to this expression is presented for high average SN. Although the case of completely correlated fading does not yield a general solution in terms of the number of cascaded links, exact solutions for average over-all error probability for 2 and 3 links are determined.
