Abstract: PURPOSE: A method and an apparatus for decoding a Reed-Solomon code are provided to efficiently decode a Reed-Solomon code by controlling the number of a modified Euclidean algorithm block and RAMs(Random Access Memory) according to the length of a code word demanded in a system. CONSTITUTION: A syndrome calculation block(110) calculates a syndrome for a received code word. One or more modified Eculid algorithm block(120) perform modified Euclidean algorithm calculation. An error location block(130) determines the location of errors based on the result of the modified Euclidean algorithm calculation. An error evaluation block(140) determines the value of the errors based on the result of the modified Euclidean algorithm calculation. An error compensation block(160) compensates for the errors based on a received code word and the determined location of errors and the value of the errors. One or more RAMs(Random Access Memory)(170) store the received code word. A control block(100) determines the number of one or more modified Eculid algorithm blocks and the number of one or more RAMs.

Abstract: PURPOSE: A channel allocation method and apparatus thereof are provided to transmit a parameter which is necessary for transmitting data by changing EHDR(Extended Header) values according to the request of a user. CONSTITUTION: A transmission apparatus transmits a message which requests information for an available bandwidth of all bandwidths(S100). A reception apparatus receives available bandwidth information. The transmission apparatus transmits parameters for a first channel through an EHDR field based on the available bandwidth information(S122). The first channel is allocated based on the parameter for the first channel.
