Research of Encoding Algorithm Efficiency in 4G Communication

The efficient method on how to calculate the physical layer communication rate matching in LTE communication system is proposed in this paper. The algorithm is based on the study of Turbo code transmission channel. The main process is that the after treatments of multiple modules such as bits collection, selection, transmission, block interleaver, block cascade and the rates of streams are matched. The key algorithm efficiency is analyzed and its performance is better than other codings. The algorithm is proved to be efficient and reliable to achieve the desired objective of high-speed and stable transmission of data in physical layer.
