Bounds on Communication with Polyphase Coding
01 April 1966
The theoretical capabilities of a "polyphase" coding-modulation scheme with additive white Gaussian noise are studied. The channel capacity of this system is found, and the error exponent estimated. Bounds are also found, on Ro (pmnx) j the maximum (asymptotic) rate for which polyphase codes can be found with maximum correlation between code words pmax .
