Abstract :
The DSP implementation and synchronisation algorithms for a low-bit-rate all-digital preambleless demodulator for mobile applications are described. This demodulator has been developed and implemented for OQPSK modulation particularly but it can work equally well for BPSK and QPSK. The performance results of implemented demodulator are provided in terms of acquisition and bit-error-rate performances
