In this work, the authors consider phase shift keying (PSK)‐type signals with very compacted spectrum and low envelope fluctuations obtained through the use of magnitude modulation (MM) techniques and stringent roll‐off pulse shaping filtering. The analytical bit error rate (BER) of PSK‐type signals combined with MM is assessed, for both flat fading and time‐dispersive channel scenarios. The authors use a Gaussian model to approximate the statistical distribution of the distortion error introduced by MM to enable a closed‐form evaluation of the BER. The proposed expression depends only on the constellation order and the Kullback–Leibler divergence of the MM factors' probability density function from the Gaussian one, and it was found to be very accurate.
