The M-ary character error probability, Pe, for a communications system employing D-fold diversity combination is derived and evaluated for the case of no fading, over the range of parameters M 2, 3, 4, 8, 16, 32, 64, 128, 256, 512, 1024 and D 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64 for Pe in the range .1 to .00001. The curves presented allow for ready determination of the additional signal-to-noise ratio required for employing diversity when it is not necessary, or when uncertainty forces it upon the receiver processing. Extensions to a thresholding receiver and to a very general class of signal fading are also made, but no numerical results are given for these latter cases. Author
