Comparison of performance of digital modulation techniques in the presence of adjacent channel interference
Abstract
The performance of four digital modulation techniques are compared to one another when each is received in the presence of adjacent channel interference. The interfering waveforms that each modulation format sees are identical to the modulation format under consideration. The four types of modulation are QPSK, 8-PSK, 16-QASK, and QPR. Upper bounds to the probability of error are derived and used to evaluate the relative merits of the different schemes.
