Abstract

In this paper a design of an optical-transparent wireless link with channel encoding and bit interleaving for enhanced digital TV transmission is proposed. For completing the system simple channel code is chosen and original all-optical schemes of a millisecond delay line and bit interleaving and de-interleaving modules are proposed and explained in detail. Considering the limitations of the used technologies and the overall delay of the wireless link, the example in the paper is for a single-wavelength 40Gbit/s signal. The interleaving degree is chosen to be 1.5ms based on the presented experimental data and theoretical analysis for burst error length. Simple evaluation of the system performance is provided and the results are compared to similar researches and discussed.
