FPGA Implementation of Interleaver in Forward Error Correction Technique
Cai Qizhong · Communications technology · 2009
This paper presents the theory of an important technology,that is,the interleaver and deinterleaver used in the forward error correction for channel coding,and proposes an interleaver design based on FPGA.The key point of the design——the way for reading and writing address,is analyzed in detail.A new method to calculate the address is given,and the implementation of interleaver is realized by properly controlling the operation of reading and writing of dual-port RAM,which is the EAB resource in FPGA chip.The design has advantages of easy realization and less resource consumption.
