Abstract

This paper investigates a variable-rate variable-power hybrid non-coherent M-FSK M-QAM system. The goal is to combine the spectral efficiency merit of M-QAM with the power efficiency advantage of M-FSK and as such extend the region of availability even at very low channel gain values. A basic system is first designed to maximize the average spectral efficiency while meeting average power and target bit error rate constraints. In addition, a peak power constraint is imposed in a more general system. The optimization procedure leads to optimum rate and power loading functions which are compared for the different modes of operation.
