Abstract

Planetary probes into the dense atmospheres of Venus, Jupiter, and Saturn may require noncoherent communication links to Earth. In this article, the capacity of noncoherent, multiple-frequency shift-keyed (MFSK) systems is determined as a function of the number of frequencies, receiver quantization, and signal-to-noise ratio. It is shown that the spacing of the quantizer levels is not critical, and that 8-level uniform quantization is essentially as good as infinite quantization.
