On the capacity of a cascade of identical discrete memoryless nonsingular channels (Corresp.)
M Simon · IEEE Transactions on Information Theory · 1970
A simplified procedure for calculating the channel capacity of a cascade ofNidentical discrete memoryless nonsingular channels is presented. The result depends only upon theMeigenvalues andMeigenvectors of any one of the subchannel transition matrices. Thus, for smallMand largeN(the usual case of interest) the result represents a considerable saving in computation relative to the standard technique of finding the overall channel transition matrix. The procedure is illustrated for anNcascade of binary symmetric channels.
