Abstract

This paper presents data and criteria to assess and guide the design of modems for coded noncoherent communication systems subject to practical system constraints of power $S$ , bandwidth $W$ , noise spectral density N0, coherence time Tc, and number of orthogonal signals $M$ . Three basic receiver types are analyzed for the noncoherent multifrequency-shift keying (MFSK) additive white Gaussian noise channel: hard decision, unquantized (optimum), and quantized (soft decision). Channel capacity and computational cutoff rate Rcompare computed for each type and presented as functions of the predetection signal-to-noise ratio $ST/N_{0}$ and the number of orthogonal signals $M = 2TW$ . This relates the channel constraints of power, bandwidth, coherence time, and noise power to the optimum choice of signal duration $T \\leq T_{c}$ and signal number $M$ .
