Recent Advancement on Design and Implementation of Low Power Digital up Counter for Digital Beamforming

Abstract

For many years, beamformers have been utilised in applications like as surveillance and RADAR, as well as communications. A high-speed, reconfigurable DUC module for digital beamforming is being developed in this project. A digital circuit that converts a complicated digital base band signal to a real pass band signal is known as a digital up converter (DUC). A DUC is made up of a mixer, a direct digital synthesiser, and a series of interpolation finite impulse response (FIR) filters that are cascaded. These filters were created with the help of MATLAB and Verilog code. Model Sim is used for simulation, while Xilinx ISE is used for functional verification, as well as FPGA implementation on the Virtex-5 Pro.
