Receiver techniques for microwave digital radio

Adaptive receiver design features and operating techniques are described which have been devised to offset the deleterious effects of multipath fading in digital radio systems. Frequency-domain and time-domain circuitry are discussed for equalizing channel distortion, and attention is also given to carrier and symbol synchronization subsystems. Height and frequency diversity are summarized for safeguarding signals from destruction by propagation effects and methods for adaptive cancellation of cross-polarized interference are described.
