An Analysis of Complex Down Mixing Filtering and Decimation in Aces (U).

Abstract

This report deals with the problems related to the use of an all- digital HF/VHF wideband receiver in a digital communication intercept system. The high output rates and large bandwidths associated with these receivers result in the need for a postprocessing system which can reduce the sampling rate and isolate, in frequency, the bandwidth of interest. Therefore, a means of digitally filtering and mixing the signal to baseband is required. Additionally, a decimation process should be included in the system. General and detailed descriptions of the Mixing, Filtering and Decimation System (MFDS) are given. Simulations of the MFDS are also provided.
