Abstract
This paper presents a coding technique which achieves, up to a frequency utilization efficiency of 2.6 b/s/Hz, better bit error rate performances than conventional 16-QAM and 8-PSK in nonlinear channels and Adjacent Channel Interferences (ACI) environment. The proposed scheme, 16-OSTQAM, is based on trellis-coding techniques but employs overlapped signal sets to compensate for the distortion and the increased required power of the 16-QAM signal. Computer simulation is carried out to clarify the performances of 16-OSTQAM compared with those of conventional 16-QAM and 8-PSK, on the same bandwidth efficiency basis and for the same amounts of nonlinearities and interferences. The proposed scheme achieves 6 dB improvement in Eb/No, up to 2.6 b/s/Hz, compared with 16-QAM, and more than 6 dB, over 2.52 b/s/Hz, compared with 8-PSK.
