Abstract

3GPP long term evolution (LTE) enhances the wireless communication standards UMTS and HSDPA towards higher throughput. A throughput of 150 Mbit/s is specified for LTE using 2x2 MIMO. For this, highly punctured Turbo codes with rates up to 0.95 are used for channel coding, which is a big challenge for decoder design. This paper investigates efficient decoder architectures for highly punctured LTE Turbo codes. We present a 150 Mbit/s 3GPP LTE Turbo code decoder, which is part of an industrial SDR multi-standard baseband processor chip.
