Troposcatter link performance in the presence of two jammers

Performance predictions of a Rayleigh fading channel are calculated for a troposcatter radio in the presence of two line-of-sight (LOS) jammers. The receiver incorporates dual main antennas and a sidelobe canceller. The countermeasure approach used is array processing. A communications approach is taken, with the goal of deriving an analytic expression for the bit error rate, in terms of the signal-to-noise ratio. After deriving the general solution, an approximation is introduced and proposed as an alternative measure of performance. It is insensitive to the fine-grain structure of the problem geometry, and it contains a minimal number of parameters, namely, the various signal energies reaching the receiver.<
