Abstract :
Studies indicate that reduced bandwidth quadrature phase-shift-keyed digital radio relay systems (RBQPSK) employing adaptive decision-feedback techniques have good spectrum utilisation efficiency coupled with robustness in the presence of distortion induced by multipath propagation. The letter discusses the practical confirmation of RBQPSK performance during multipath propagation on a 6 GHz, 51 km long test link in East Anglia.
