Comparison of modulation
Techniques of digital
Radio
This paper
describes and summarizes the characteristics of the modulation techniques most
applicable to digital radio. The modulation techniques discussed are quadrature
amplitude modulation (QAM), binary and quaternary phase-shift-keying (BPSK,
QPSK).Functional descriptions of these schemes are provided and their
performance is compared in a series of tables summarizing the results of the
literature of the past 20 years. The modulation schemes are compared with
respect to performance, complexity, probability of error, spectral density and
bandwidth. Mainly three modulation techniques are used for comparison that are
quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM) and
Binary phase shift keying (BPSK).
