Title: | A 0.16nJ/bit/iteration 3.38mm 2 turbo decoder chip for WiMAX/LTE standards | Authors: | AN-YEU(ANDY) WU Lin, C.-H. Chen, C.-Y. Chang, E.-J. AN-YEU(ANDY) WU |
Keywords: | LTE; Multi-standard; Turbo Decoder; WiMAX | Issue Date: | 2011 | Start page/Pages: | 168-171 | Source: | 2011 International Symposium on Integrated Circuits | Abstract: | This paper presents a turbo decoder chip design supporting distinct convolutional turbo code schemes in WiMAX and LTE systems. A contention-free vectorizable dual-standard interleaver is proposed to enhance the hardware utilization. Moreover, a warm-up free parallel MAP decoding is proposed to improve the throughput rate. The overall VLSI architecture of the proposed CTC decoder is presented for supporting the WiMAX/LTE systems. This chip fabricated in a core area of 3.38 mm 2 by 90nm CMOS process is measured at 152 MHz with a power consumption of 148.1 mW and a throughput rate of 186.1 Mbps. This chip achieves a high area efficiency of 0.36 bit/mm 2 and a low energy efficiency 0.16 nJ/bit/iteration. © 2011 IEEE. |
