doi:10.3969/j.issn.1000-0801.2011.06.017

Abstract

Abstract:

LTE system requires reliable communication of higher standard，which depends on channel coding performance to some extent.In this paper，decoding algorithm of Turbo codes in LTE system is researched and an improved algorithm is presented based on the Max-log-MAP and Log-MAP algorithms.Theoretical analysis and simulation result show that the performance of this improved algorithm is promoted ulteriorly，it is easy to hardware implementation and has lower complexity.

Key words: LTE, Turbo codes, Max-Log-MAP, improved algorithm
