Abstract
Adaptive burst coherent demodulation scheme is studied. This scheme is suitable for applications having burst slots in fast flat fading environment such as TDMA radio communication systems. It coherently demodulates individual bursts of TDMA symbols using an infinite impulse response (IIR) adaptive phase tracking system. This adaptive structure can track time-varying phase jitter introduced by fast Rayleigh fading channels. So, any modification is not needed in the conventional transmitter. In the receiver, the adaptive parameter set for the highest Doppler frequency considered can be used without changing for lower cases, thus requiring no fading statistics estimation. The error-floors caused by the Doppler spread are lowered up to one third of that in conventional differential detection.
