PDF-August SLWA APPLICATION NOTE BUILDING DIGITAL PSK AND QAM DEMODULATORS USING THE GC

0 INTRODUCTION This report describes how one can use the GC2011 Digital Filter the GC3011 Digital Resampler and the GC3021 Carrier Removal chips to build high performance digital demodulators for most BPSK QPSK and QAM radio signals In order to simpl. By Arne Svensson Fellow IEEE ABSTRACT A major disadvantage with fixed modulation nonadaptive on channels with varying signaltonoise ratio SNR is that the biterrorrate BER probability performance is changing with the channel quality Most applications Digital data must be modulated on an analog signal that has been manipulated to look like two distinct values corresponding to binary 1 to binary 0.

A digital signal is superior to an analog signal because it is more robust to noise and can easily be recovered, corrected and amplified. For this reason, the tendency today is to change an analog signal to digital data. In this section we describe two techniques, . @CS.NCTU. Lecture 2: Modulation and Demodulation.
