Dual-tone MFSK for frequency-hopped spread-spectrum multiple access
Thomas Aaron Gulliver, Steward H. C. Ting · 2002
This paper investigates a dual-tone MFSK signalling technique for a frequency-hopped spread-spectrum communication system. It allows for multiple access communications with less transmission bandwidth and thus greater number of users than conventional MFSK. Both uncoded and coded dual-tone MFSK systems are considered in multiple access interference and additive white Gaussian noise with and without Rayleigh fading.
