Abstract :
An error-free facsimile signal transmission scheme over the Japanese digital cellular standard air interface (three-channel TDMA) is described. To mitigate multipath fading effects and to achieve high transmission throughput, an efficient ARQ scheme, WORM-ARQ (ARQ with window-control operation based on reception memory) is proposed. Throughput efficiency with WORM-ARQ is evaluated through both laboratory and field experiments, together with computer simulation. The WORM-ARQ scheme has been applied to G3 facsimile signal transmission. Error-free document transmission can be realized at an average throughput of 4.8 kb/s even with an average channel bit error rate of 10-2
