Bounds on Communication with Polyphase Coding
Aaron D. Wyner · Bell System Technical Journal · 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(ρmax), the maximum (asymptotic) rate for which polyphase codes can be found with maximum correlation between code words ρmax.
