Abstract

The paper deals with the optimal choice of the system parameters in an HF digital radio link employing 2 FSK modulation and limiter/discriminator demodulation. Using a simulation approach for short time performance evaluation it is shown that, for this type of system, the optimal choice is not the same as in the case of the ideal channel and is independent of the SNR value at receiver point. The effect of the filters´ shape is also analyzed, showing that the best performance is obtained somewhere in the middle between very steep filtering and Gaussian-like transfer function behaviors
