Error correction for polynomial block codes is achieved without prior evaluation of power sum symmetric functions. The received word R (z) is reduced mod G (z), the generator of the code and a function F (z) of error locator polynomial W(z), errata values Y and code dependent functions f(x.sub.i) of...http://www.google.com/patents/US4633470?utm_source=gb-gplus-sharePatent US4633470 - Error correction for algebraic block codes
