Abstract :
An approach to designing power- and bandwidth-efficient trellis-coded partial response signaling (TCPRS) is presented. Two theorems make it possible to find good TCPRS codes based on good codes for trellis-coded modulation (TCM). A class of good TCPRS codes is thus found. The free distance and asymptotic coding gain are calculated, and it is shown that a maximum coding of 4 dB can be achieved with this class of codes. The distance structure of this class of codes is discussed, and the performance at medium signal to noise ratio (SNR) is presented. As compared to TCM codes, the class of TCPRS codes features a degradation of 2 to 2.5 dB at extremely high SNR and a degradation of only 1 dB at medium SNR, while the spectral behavior is improved
