Abstract :
Spectral shaped quaternary-phase transition FSK (ss-QTFSK) is proposed and then its error performance improvement using an efficient block-coded modulation is confirmed. Error performance improvement in E b/N0 reaches up to 3 dB to achieve a BER of 10-3 in the case coding efficiency being 0.9 (the additive Gaussian channel and a differential detection/Viterbi sequence estimation are employed for the above analyses)
