Error performance improvement of bandlimited QTFSK assisted by an efficient coded modulation and Viterbi sequence estimation
Description
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/sub b//N/sub 0/ reaches up to 3 dB to achieve a BER of 10/sup -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). >
