Optimisation of parameters in an MFSK transmission system

An optimisation technique for maximising the information throughput of an M-ary frequency-shift keyed (MFSK) transmission system is described. An upper bound for the error-free throughput of the system in the presence of additive white Gaussian noise (AWGN) for different numbers of tones, M, is derived. From this, the optimum range for M can be identified.
