We consider the problem of transmission of a sequence of real data produced by a Nyquist sampled band-limited analog source over a band-limited analog channel, which introduces an additive white Gaussian noise. An analog coding scheme is described, which can achieve a mean-squared error distortion proportional to (1+SNR)-B for a bandwidth expansion factor of B/R, where 0 < R < 1 is the rate of individual component binary codes used in the construction and B ≥ 1 is an integer. Thus, over a wide range of SNR values, the proposed code performs much better than any single previously known analog coding system.
