Speech transmission and reception system for digital communication |
摘要 |
A transmission device performs encoding by a speech encoding portion including a speech encoder and error correction encoder, and transmits a continuous signal without any further processing. A reception device receives the continuous signal and performs channel decoding and speech decoding as one unit by a speech decoding portion including a soft-decision error correction decoder and a soft-decision speech decoder. Thus, a transmission and reception system performs an accurate signal reproduction without removing the signal including a normal bit error rate by correcting the error by the speech decoder.
