Research on Digital Baseband Converting Methods in Interference Measurement System

Abstract:

Focused on DBBC(digital baseband converter) which is used in interferencemeasurement system, two typical digital baseband converting methods are introduced. Using parallel structure and poly-phase structure to improve the orthogonal mixing method, the method based on parallel conversion is proposed. Combining the efficient PFB(poly-phase filter bank) channelization with theflexible orthogonal mixing , the method combining PFB channelization with the orthogonal mixing is proposed. This method can realize full spectrum received.Considering the efficiency and power, the method combining PFB channelization with the orthogonal mixing is better.
