Forward Error Correction (FEC) is a technique used to control errors in data transmission over unreliable or noisy communication channels. It involves encoding the message with an error correction code, allowing the receiver to detect and correct a limited number of errors. FEC can be applied in situations where re-transmissions are costly or impossible, and is widely used in modems and cellular networks. Different codes are suitable for different conditions, and some advanced FEC systems come close to the theoretical maximum given by the Shannon channel capacity.

This course explores the role of randomness in computation and pseudorandomness, focusing on the applications in error-correcting codes, expander graphs, randomness extractors, and pseudo-random generators. The course will also address the question of derandomization of small-space computation. Prerequisites are unspecified, but the course content suggests a high level of expertise.
