9-6 TCPR(1,1)方式とTCPR(1,-1)方式の所要SN比比較 [in Japanese] Required SNR Comparison of TCPR(1,1) System and TCPR(1,-1) System [in Japanese]
Access this Article
TCPR(Trellis coded partial response) system is well known a fundamental idea for improving code gain deseribed by minimum free Euclidean distance. In this paper, we firstly study required SNR characteristics of both TCPR(1,1) and TCPR(1,-1) systems on the code rate η=4/5 and bit error rate BER=10^<g;-5>. The simulation results show the superiority of TCPR(1,1) system. Secondarily, we investigate the dependency of the code rate on TCRP(1,1) system and confirm that the trend becomes remarkably at the normalized linear density K〓2.4.
