Hardware and Energy-Efficient Stochastic LU Decomposition Scheme for MIMO Receivers

  1. 1. E-Mail: pvrieeeprojects@gmail.com, Ph: 81432 71457 Hardware and Energy-Efficient Stochastic LU Decomposition Scheme for MIMO Receivers Abstract In this paper, we design a hardware and energy-efficient stochastic lower–upper decomposition (LUD) scheme for multiple-input multiple-output receivers. By employing stochastic computation, the complex arithmetic operations in LUD can be performed with simple logic gates. With proposed dual partition computation method, the stochastic multiplier and divider exhibit high computation accuracy with relative short length stochastic stream. We have designed and synthesized the stochastic LUD with CMOS 130-nm technology. According to the postlayout report, the hardware efficiency of the stochastic LUD is as high as 1.5× compared with the exiting LUD methods, and the energy efficiency is also higher than the state-of-the-art LUD when the matrix dimension is 8 × 8 and larger. Tools :  Xilinx 10.1  Modelsim 6.4b Languages :  VHDL / Verilog HDL
