Abstract
A separate operational section for determining the degree of a polynomial is provided to increase the process speed in determining both error locator and evaluator polynomials. When a received word is decoded based on the error location found, the received word is stored in a memory and corrected and output through the designation of the address. The formula ##EQU1## is derived from the error locator equation ##EQU2## and the value of which satisfies .sigma.(.alpha.)=0 is determined to increase the process speed. The decoder and the encoder share part of the hardware to make the system compact.
