Abstract :
Bounds on the capacity of a class of digital communication channels are derived. Equating the bounds on capacity to rate-distortion functions of (typical) sources in turn produces bounds on the performance of a class of digital communication systems. For ratios of squared quantization level to noise variance much !ess than one, the power requirements for this class of digital communication systems are shown to be within approximately 3 dB of the theoretical optimum.
