A 30 Mbits/s adaptive delta modulated microwave system

An experimental 30 Mbits/s digital microwave transmission system has been developed. This thesis embodies the circuit theory, design techniques, and implementation characteristics of the system. The transmission system consists of the baseband digital processes, as well as the RF subsystem in both the transmitter and the receiver. It employs a fast Adaptive Delta Modulator to encode analogue signals with sampling rates exceeding 30 MHz and bandwidths greater than 1 MHz.
