Abstract :
A theory is developed, based on bench measurements with two quasi-synchronous data signals, which predicts the mean bit error rate (b.e.r.) and the mean 64-bit word failure rate experienced at stationary receivers in the overlap area of two quasi-synchronous transmitters. The signals from the transmitters suffer independent Rayleigh fading. The performance with a carrier frequency difference of a few hertz is shown to be 2 dB better, and with a larger difference (18 and 180 Hz) to be 5-10 dB worse, than with a single transmitter.
