In this paper, the concatenated system of phase preceding and trellis coded modulation (TCM) is investigated. Simulations of throughput (Rb) of 2 bits/sec/Hz show that phase precoding gains at BER of 10E-6 by 6.5 dB and 2.5 dB for rate 2/3 8PSK-TCM with four and eight state code respectively, compared to sub-optimum soft output equalization (SSE) at the receiver with the same TCM-codes. This pure precoding is verified on uncoded-QPSK in which more than 30 dB is gained compared to SSE. In addition at Rb of 3, a newly designed multiple-TCM (16PSK-2MTCM, 8 states) with precoding confirms this concatenation system for powerful ISI cancellation by achieving more than 1.5 dB of gain
