Partial removal of transmission errors in digitally encoded speech
Robert JC Steele · Electronics and Power · 1978
Error protection coding is often used to combat the effect of transmission errors in binary encoded speech, but, if data throughput is to be kept constant, it requires an increase in transmission bit rate. An alternative approach, which does not use a protection code, decodes the erroneous speech at the receiver, inspects it, deduces the effect of transmission errors, and partially corrects it using a simple statistical hypothesis
