A SIMPLE AND EFFECTIVE HYBRID CODING/DECODING SCHEME

Abstract

A simple hybrid coding/decoding scheme for the Gaussian channel is described resulting in a reasonable gain of performance compared with the corresponding single stage code, The undeteded bit error probability is estimated to be less than 10^(-5) and the probability of detected errors (deleted data) less than 1% at a signal-to-noise-ratio E(b)/N(o) of 2.3 db. The deletion rate decreases by an order of magnitude for each additional .15 db of signal energy.
