The Troposcatter Modem Receiver includes a combiner, demodulator, baseband filter, a complex coefficient forward equalizer, a detector and a feedback circuit. The combiner is a linear maximal-ratio combiner and receives a plurality of input signals at an intermediate frequency and generates a combined output signal for presentation to the demodulator. The demodulator produces a demodulated signal which is filtered by the baseband filter prior to being presented to a first input of the equalizer. The output of the equalizer is forwarded to the detector which produces an output signal. The signal is fed back by way of the feedback circuit to a second input of the equalizer to modify the output signal.
