Abstract
A device useful in personal digital cellular (PDC) mobile telecommunications. The device is formed of an application specific integrated circuit (ASIC) chip and a digital signal processor (DSP) chip. The ASIC at least converts between digital modulated signals and analog ones. The DSP chip at least digitally modulates and demodulates the digital modulated and demodulated signals, digitally processes the demodulated signals to and from speech and control channel signals and performs vector sum excited linear prediction (VSELP) compression and decompression.
