چکیده:

Reliability and data rate are two basic factors on QoS in mobile communication networks. This can be achieved by addition of redundancy bitsi.e error detection and correction codes) to refer to reliability. Reed-Solomon coding is one of the most important schemes for this purpose to achieve error correction. In this paper a pipeline approach for a RS decoder is proposed to reduce the processing time. In the pipeline architecture the number of steps to performis in three stages, so the ideal speed up must become1.8. Because of the data dependencybetween the stages, the achieved speed up is 1<S<1.8. The hardware description language (HDL) method is employed to hardware synthesis the Reed-Solomon encoder and decoder on FPGA devices.
