On the effect of phase error in digital communication systems
Abstract
An analysis is briefly presented showing the effect of carrier phase error due to jitter on the error rate in digital communication systems. The information bearing signal is taken to be impaired by peak-limited additive interference and multiplicative noise, such as carrier phase jitter. Probability of error and distance function due to slowly varying phase jitter (phi less than pi/2) and computer simulation results on the system performance for different SNRs corresponding to bit rates 10.8, 14.4, 18.0 and 21.6 kbit/s and various channel bandwidths 1.2, 2.4, 3.6 and 4.8 kHz are presented along with the possibility of minimization of such effects using a decision feedback equalizer. The results show a significant improvement of power by 1.1 dB per degree phase error which can be achieved at an error rate of 0.001 over the range of SNR values of 32-40 dB.
