OPTIMUM PULSE TRANSMISSIONS FOR MULTIPATH CHANNELS,

Abstract

The problem of modulation and demodulation tech niques for communicating through fluctuating multipath channels has been considered in rather general terms by several authors. In this report the performance of an incoherent M-ary communication systemepperating via a fluctuating multipath channel is computed under very restric tive conditions on the channel behavior, namely, that the received signal consists of resolvable, independently Rayleigh fading paths each of which has been corrupted additively by indepen dent gaussian noise. Probability of error expressions are given for the M-ary receiver which are generalizations of results obtained earlier by Turin, Hahn, and Pierce. From these expressions the optimum time duration for pulse transmissions is computed for two channels-the orbital dipole channel and the moon. 9(Author)
