One of the most popular approaches to improving bandwidth efficiency is the use of signals with inter-symbol interference (ISI). In this paper bandwidth-efficient partial response signals (PRS) are analyzed in combinations with 4-QAM, 8-QAM and 16-QAM signal constellations and recursive systematic convolutional codes. We simulated transmission of encoded data through AWGN channel using the optimal PRS, each pulse shape gave maximal free Euclidean distance for chosen constellation and bandwidth… CONTINUE READING
