Book Description
Formulas for the error probabilities of non-orthogonal M-ary signals under optimum phase-coherent and phase-incoherent reception are derived in the form of previously untabulated single and double integrals. Two modes of reception are considered. In the first, one of M equal energy equiprobable signals is known to be transmitted during a baud of T seconds and subjected to additive white Gaussian noise. There is no fading and only one path is available for communication (no multipath). In the second mode of reception, the only difference is that a threshold is incorporated in the receiver. If the largest correlation value is less than the threshold, a decision is made that no signal was transmitte ; if the largest correlation value exceeds the threshold, the signal corresponding to that particular correlation value is decided to have been transmitted. Applicability of the results to related problems and non-white and nonstationary noise is discussed, and bounds on performance in such situations are pointed out. (Author).

Book Description
The error probabilities for some general classes of non-orthogonal M-ary signals are derived under conditions of synchronized phase-coherent reception in a non-fading single path channel subject to additive white gaussian noise. The results are in the form of untabulated low-order multiple integrals which are amenable to computer evaluation. (Author).

Book Description
The error probabilities for uncoded multiple alternative transmission of the output of a discrete data source are derived quite generally and numerically evaluated for a sample case. Specifically, the source emits D-ary equiprobable messages (information digits) which are represented by (associated with) an M-ary alphabet (transmission digits) so as to minimize the average symbol length in the M-ary representation. One of the M signals is transmitted and an M-ary decision made in the receiver. A sequence of these received digits is then reassociated into the information alphabet. For the particular case of phase-coherent reception in a non-fading additive Gaussian noise channel, comparison of different transmission alphabets (different M) for a given source (given D) is accomplished under the constraints of equal source data rate, average signal power, and average noise power. No bandwidth constraints are imposed. One of the major conclusions is that if the ratio of signal energy per bit interval to noise power density is less than 1n 2, the optimum transmission alphabet size to minimize the average D-ary error probability has M equal to D; if however, this signal-to-noise ratio is larger than 1n 2, the larger M is, the lower is the value for the average error probability.
