Abstract :
The optimum adaptive receiver for the line of sight microwave transmission channel is developed assuming that the channel consists of a purely multipath structure yielding signals received at various delays, and that the variations of the parameters of the channel are much slower than the data bit rate. The receiver is adaptive in the sense that it contains a record of the channel parameters in a memory. The time constant of the smoothing filter is adjustable. An expression for a figure of merit is developed and presented. An experimental model of the receiver is described and preliminary experimental results are presented.
