Quadratic Rotation decomposition (QRD) based recursive least squares (RLS) algorithm can be used in variety of communication applications and its low complexity implementation can be of interest. In this paper we have presented FPGA implementation of QRD based RLS algorithm using Coordinate Rotation by Digital Computer (CORDIC) operator. FPGA resource estimates along with actual implementation results illustrating the weight calculation delays have also been presented presented.

Abstract


Quadratic Rotation decomposition (QRD) based recursive least squares (RLS) algorithm can be used in variety of communication applications and its low complexity implementation can be of interest. In this paper we have presented FPGA implementation of QRD based RLS algorithm using Coordinate Rotation by Digital Computer (CORDIC) operator. FPGA resource estimates along with actual implementation results illustrating the weight calculation delays have also been presented presented.
