Rate-adaptive transmission techniques in the context of runlength-limited codes for atmospheric optical communications; [Técnicas de codificación de longitud constreñida de tasa adaptativa en sistemas de comunicaciones ópticas atmosféricas]

Abstract

In this work, the use of a rate-adaptive transmission scheme based on silence periods and trea-ted as runlength-limited (RLL) sequence is proposed in order to mitigate the adverse effect of atmospheric turbulence in optical free space communications. Results show that the bit error rate obtained by the proposed scheme is similar to that of the Viterbi algorithm with a much lower computational load. © Sociedad Española de Óptica.
