title: Mimo Systems Low complexity SVD Implementation Analysis
ispublished: pub
subjects: telecomunicaciones
subjects: matematicas
abstract: This paper analyses the implementation of the singular value decomposition (SVD) using approximation to the exact computation for MIMO systems in the case of modulation-mode and power assignment set-up. The study developed in the paper focuses on the use of low complexity algorithm with low computational load oriented to the use of devices with limited resources as FPGA, highlighting some of the advantages and drawbacks against more sophisticated devices. The implementation of the SVD is analyzed through the algorithms that efficiently perform the required computations, seeking for computationally efficient solutions that provide parallelism and low complexity. The CORDIC algorithm seems to be a good candidate for this task since it can efficiently compute the singular value decomposition. It is shown that this algorithm provides an efficient tool for SVD computation with appropriate accuracy and the computational complexity obtained and the required resources make it feasible to be implemented on an FPGA device. System performance degradation is analyzed compared with conventional and exact method for SVD obtaining some key conclusions.
