Abstract
A study is reported of ´double-jump´ Nyquist channel filters which lead to reduced spectral spreading and an important bit error rate (BER) performance in nonlinearly amplified (NLA) mobile radio systems. In linearly amplified systems the filter retains the intersymbol-interference free properties of Nyquist filters and has the advantage of lower overshoot than the conventional raised cosine (RCS) filters. This reduced overshoot power (ROP) filter leads to a 1 dB system gain over conventional RCS filtered 16-QAM systems in NLA channels
