Abstract

An analysis is made of the performance of three types of quadrature partial response signaling (QPRS) systems using complex one-sided and two-sided transversal filters with additional decision-feedback (DF) taps in the presence of single continuous wave (CW) interference and additive white Gaussian noise. It is found that both DF filters can suppress not only CW interference but also filtered noise which is necessarily colored by passing through the QPRS receive filter, while decoding binary data signals from ternary QPRS signals. It is also shown that the duobinary system has the best performance of the three types of QPRS systems when the frequency of CW interference is low.
