Hybrid Arithmetic Coding of Securities Trading Data Compression
Xiaohu Yang · Jisuanji gongcheng · 2010
By analyzing the problems while transmitting securities trading data,necessity of data compression is indicated.This paper proposes a hybrid arithmetic coding for messages of Securities Trading Exchange Protocol(STEP).The coding improves adaptive binary arithmetic coding by using template-based binarization scheme and independent source model.Experimental results show that hybrid arithmetic coding provides a much better compression ratio and slightly faster processing time than adaptive binary arithmetic coding.
