FPGA implementation of LTE turbo decoder using MAX-log MAP algorithm

Abstract

Implementation of an efficient turbo decoder with low complexity, short delay and insignificant performance degradation is currently a quite challenging task. The paper presents an implementation of a 3GPP TS 36.212 LTE turbo decoder. The design of the turbo decoder has been optimized to achieve efficient FPGA resource utilization. This design can be useful for applications, which is critical to resource utilizations, but do not need high throughput.
