Abstract :
A family of weighted-quadrature-amplitude-modulation (WQAM) schemes is introduced and analyzed. One of the staggered WQAM (SWQAM) schemes has low spectral sidelobes, even after hardlimiting, and its performance in an adjacent-channel interference (ACI) environment is superior to that of the QPSK; SQPSK, MSK, and SQORC. The subscriber networks and the highest data-rate systems operating in a nonlinear channel are preferable applications.
