Transmission of digital data over a rayleigh fading channel

In a microwave mobile telecommunications system, a digital message must be transmitted several times to overcome the effects of Rayleigh fades that characterize this channel, and thus ensure a high probability that the message is received error-free. An analytic approach to an evaluation of the comp...

Some fade statistics that have been used are presented. The upper bounds are derived on probability of the transmission failure for three different schemes.
