Abstract
The feasibility of using digital techniques for the coherent demodulation of wideband signals was investigated. Several different design approaches and analysis methods were considered. It was found that the processing requirements to achieve good accuracy for pulse and other wide-band signals can be minimized through appropriate choice of intermediate frequency, the use of half-band finite impulse response filters, and the application of decimation. This suggests that an application specific integrated circuit implementation of a digital coherent demodulator should have potential cost and performance advantages over existing analog approaches.
