Abstract
DVB-T is a transmission standard that enables good reception even when the transmission channel is subject to frequency-selective fading. When DVB-T is used for a mobile microwave link, flat fading can occasionally occur. In this article, a time interleaving layer is proposed that makes the transmission more rugged under flat fading conditions. The proposed mechanism involves an additional Reed-Solomon coding step and a modified data transmission order, and preserves the DVB-T layer of the communications channel.
