ABSTRACT:
Sequential encoding of Reed-Solomon codes using a discrete time delay line, a single adder, and a single multiplier provides efficient encoding of Reed-Solomon codes with or without interleaving. The encoder utilizes a clock whose rate is r times the symbol rate where r is the redundancy of the code. The finite field operations are performed in a sequential manner requiring only one finite field multiplier and one finite field adder. All memory elements are consolidated into a discrete time delay line which can be implemented with a random access memory. The encoder can be easily reconfigured for changes in generator polynomial of the code, the amount of redundancy, and interleaving depth.
