Abstract

In this paper

rate matching is first implemented for the tailbiting convolutional codes of the Time Division-duplexLong Term Evolution（TD-LTE）systems.After in-depth research on the tailbiting convolutional code rate matching algorithm in the 3GPP protocol and the TD-LTE wireless integrated test system

a fast implementation scheme realized by using a DSP chip is proposed.The results of the decoding program running in CCS3.3verify the feasibility and effectiveness of the scheme and its optimization strategies.
