Abstract:
1. A method, comprising: segmenting a first data stream into packets of a predetermined fixed-size for a burst-mode transmission over a wireless channel, wherein the transmission is subject to a first periodic blockage, wherein, for a given duration of time, the first periodic blockage comprises a recurring blockage of a given duration occurring at a period of regular intervals; applying a forward error correction (FEC) outer code to the packets of the first data stream for recovery of packets subjected to the first periodic blockage, wherein the application of the FEC outer code comprises grouping the packets of the first data stream into a plurality of groups of n packets in each group and applying an error correction code to each group of packets, wherein the grouping of the packets comprises interleaving the packets of the first data stream so that each group contains a number of packets subjected to the first periodic blockage that does not exceed the error correction capabilities of the error correction code applied to the group, and wherein the number of packets n in each group of packets of the first data stream is based on one or more of the period of the recurring blockage and the blockage duration of the first periodic blockage; and transmitting the first data stream over the wireless channel.
