Design and Implementation of VHDL for High Speed Interleaver in Tactical Data Link

This paper introduces the channel coding of data link system, and analyzes the principle and algorithm of interleaved codec in data link. Based on this, a convolutional interleaving codec for RS (204, 188) code is designed and implemented by VHDL. The data delay is realized, and the function of convolutional interleaving is completed. The design has the advantages of simple implementation and low resource consumption.
