Maximum likelihood sequence detector for dicode pulse position modulation

It is shown that the dicode pulse position modulation (DiPPM) scheme, presented in this study, demonstrates several key advantages in comparison with other existing PPM schemes, because of the compact structure and efficient recovery process of the clock signal. An error corrector for the DiPPM scheme is presented, where experimental results prove the theoretical expectations of a previous publication. Thus, it is demonstrated that DiPPM with the use of a maximum likelihood sequence detector (MLSD) error corrector, significantly reduces or eliminates errors incurred during the transmission. Comparison of and discussion on the outcomes of a DiPPM system with and without the error corrector are included
