1985 256-QAM Modem Performance in Distorted Channels
abstract
Performance degradations of 256-QAM modems in distorted channels are studied in this correspondence. Illustrative linear, parabolic, and sinusoidal amplitude and group delay channel distortions, caused by filter imperfections and/or by selective radio fades, are investigated. To enable an easy comparison with 64-QAM systems, we present the degradations of these systems in the same figures as those of 256-QAM modems. It is shown that linear (slope) group delay and sinusoidal (ripple) amplitude distortions cause the most significant performance degradations.

1985 Multilevel PRS/QPRS Above the Nyquist Rate
abstract
An improved efficiency partial-response signaling (PRS) and quadrature partial-response signaling (QPRS) data filtering strategy, which enables a higher transmission rate (more symbols/s/Hz) than feasible with conventional PRS and QPRS systems, is introduced. With the use of our technique, a smaller number of signal levels (states) can be chosen for specified spectrally efficient applications; thus, an increase inS/Nimmunity is obtained with a lower cost and simpler hardware implementation.
