Forward error correction with flexible matrix for dynamic input data rate
Described herein are systems, methods, and other techniques for performing forward error correction in a communication system. A set of data blocks to be transmitted over a wireless channel are received. Rows of a flexible matrix are formed using the set of data blocks based on arrival times of the set of data blocks, each of the rows corresponding to a different time window. A set of random parity blocks are computed by performing row-wise parity operations on the flexible matrix. A set of burst parity blocks are computed by performing column-wise parity operations on the flexible matrix in accordance with a burst parity computation scheme. The set of data blocks, the set of random parity blocks, and the set of burst parity blocks are transmitted over the wireless channel to a receiver.

Adaptive forward error correction in low-power wide area networks (LPWANS)
In one embodiment, techniques for adaptive forward error correction (FEC) in Low-Power Wide Area Networks (LPWANS) are disclosed. The techniques may include determining, by a process, for a block of messages transmitted through a computer network with forward error correction, whether any unrecovered data loss occurred during transmission; increasing, by the process, a level of forward error correction used to transmit through the computer network in response to unrecovered data loss; and/or decreasing, by the process, the level of forward error correction used to transmit through the computer network in response to no unrecovered data loss.
