A6struct 32 kb/s Adaptive Differential Pulse Coded Modulation (ADPCM) is a widely accepted high quality speech coding algorithm. Single chip devices exist for 32 kb/s ADPCM. "his algorithm requires a relatively large bandwidth and does not perform exceptionally well in noisy wireless environments, The 16 kb/s lowdelay code escited linear prediction (LDCELP)(More)
This paper presents a low complexity, low delay variable rate speech cd ing method suitable for low power (CDMA or TDMA) indoor wireless communications. The indoor wireless communications channel is characterized by relatively deep fades resulting in bursty errors. A robust speecb codec is required to combat this bursty nature. Low power operation is(More)
