Title: Cross-Talk in QPSK Communication Systems
Authors: Tien Manh Nguyen
Owens, Yvette
Issue Date: Feb-1994
Citation: USA
Abstract: This report investigates the effects of cross-talk on the Bit Error Rate (BER) performance of QPSK communication systems. There are four different sources that can cause cross-talk in QPSK systems, namely, a band-limited channel, asymmetry in filters, phase imbalance between the channels, and imperfect carrier tracking. This report emphasizes the last two problems (where either phase imbalance in the local VCOs or imperfect carrier tracking exists).
