Error-free high-speed data transmission protocol simultaneously applicable to both wire and mobile radio channels

摘要: The authors describe an integrated mobile communications traffic analysis of voice, data and image by a cellular telephone system. They report the results lost-call simulation under various conditions. A newly developed universal protocol, ARQ-based protocol adapted for land transmission, is considered, along with forward error correction (FEC)-based which adaptive control adopted high-speed transmission. It found that service can be provided present analog When used 4800 bit/s CCITT V.27 ter modem, this increases throughput to 120%. This new handle transmission on burst error-prone radio channels if bit rate (BER) less than about 5*10/sup -2/. >
