This paper investigates the bene ts of link adaptation according to the propagation conditions using multi-rate vocoders and channel coders. A multi-rate source and channel coding (MRC) system trades-o the source codec bit rate against channel codec bit rate according to the prevailing channel conditions. MRC systems continuously recon gure transmission(More)
As digital speech transmission technology becomes more widespread. the trend is to find robust and low complexity bandwidth-eflicient algorithms for speech coding. As forerunners in this area. the LPC based schemes like MPLPC [1]. RPE [2]. CELP [3]. etc and recently. CELP-BB [4]. have been extensively reported. With its reasonable complexity and high(More)
