Massarella, Alistair J. and Sibley, Martin J.N. (1992) Experimental error correction results for optical digital pulse-position modulation. Electronics letters, 28 (18). pp. 1684-1686. ISSN 0013-5194

Original practical and theorical results are presented for the detection and correction of errors in a direct detection optical ( = 1.523 µm) digital pulse-position modulation (digital PPM) system. These results show the degradation in system performance due to interframe interference and an original method of correcting this type of error is presented. This error correcting method was then used to enhance the performance of a Reed-Solomon (RS) coded, digital PPM system
