Abstract
A single polynomial expanderis time multiplexed to produce firstly a modified syndrome polynomial T(x) and then an erasure located polynomial Λ(x). T(x) is supplied to a key equation solving unitwhich solves the key equation to calculate an error locator polynomial σ(x) and an errata evaluator polynomial ω(x). These polynomials σ(x), Λ(x) and ω(x) form three inputs to polynomial evaluatorsand a Forney blockfor determining the location and magnitude of each symbol error and symbol erasure, allowing the received codeword to be corrected in a correction block. Optionally, a transform blockis provided to avoid unnecessary delay and improve throughput when decoding shortened codewords.
