Abstract

The performance of the Reed Solomon coder/decoder for an ADSL modem is studied. The proposal incorporates a new faster parallel structure for the RS coding/decoding part of the modem that exploits the single latency operation of the device. The modem is fully compatible with the existing standard of T1E1.4 ANSI Standard Group and ADSL Forum requirements. The proposed structure was simulated and the results confirmed significant savings. Only the coding/decoding part of the modem was simulated. The simulation results of the parallel structure showed approximately 50% improvement in the speed of the RS coding/decoding operation. The correcting possibilities of the RS code were also confirmed and shown in the simulation results. The paper is organized as follows. The specific structure of the modem is presented. A brief introduction to Reed Solomon codes for ADSL applications is then given. Finally, the simulation results are presented
