Abstract
(English)
This work provides an analytical method for evaluating the performance of upper layer forward error correction (FEC), when used together with interleaving on land mobile satellite channels, in terms of residual (after decoding) packet loss rate. In addition, simulations highlight the overheads introduced by this technique, which depend on the channel statistics, in terms of additional packet delivery delay, bandwidth consumption, and computation power required. We will show why the interleaver is mandatory in some environments, due to the severe disruptive characteristics of the channel, according to measurement campaigns promoted by the European Space Agency. This analysis provides the expression of the residual packet loss rate, when systematic FEC coding blocks are interleaved at packet level (i.e. when a cyclic redundancy check and a sequence number identify a precise data unit). This method can be employed for performance evaluation of recent and future mobile communication systems that take advantage of upper layer FEC and interleaving techniques.
