Abstract

This paper describes an efficient coherent demodulation algorithm aiming at the receiver in Terrestrial Trunked Radio (TETRA) communication system. The algorithm proposes frequency offset error twice-estimation and sectioned phase offset compensation to achieve the high precision in carrier synchronization. Odd-even decision is then proposed in the algorithm to avoid signal noise ratio (SNR) loss in differential demodulation. The simulation has confirmed that the precision of frequency offset error twice-estimation is better than that of data-aided (DA) estimation and that compared with differential demodulation, the bit error rate (BER) performance of coherent demodulation is much better.
