Design and Realization of IF Digital Demodulator based on Software Radio

摘要：

The paper introduces a design based on high speed a/D,digital down converter,large capability SDRAM and hardware platform of high speed digital signal processor using and the realization of demodulation of FSK,BPSK,QPSK,ASK in different speed by different algorithms. The intermediate frequency digital demodulator has the feature of flexibility and fast refresh. The paper introduces the structure composition and working principle of the demodulator,and theoretical derivation and application description of the algorithm involved in digital demodulation.

关键词： software programmable digital down converter digital signal processing demodulation algorithm.
