| Abstract: | Nowadays,the interleaver-and-deinterleaver technology is widely used in digital communication systems,thus to reduce data error,such as DVB system.This paper describes the principle of interleaver-and-deinterleaver technology,proposes a design scheme of RS-oriented convolutional interleaver in conformity with the DVB-C standard.The paper analyzes in detail the generation of read-address and write-address,and provides the simulation waveform of the proposed interleaver. |
