This document discusses the implementation of a CORDIC (COordinate Rotation Digital Computer) algorithm in an OFDM-based wireless local area network receiver. It first provides background on the CORDIC algorithm and its basic principles. It then describes the design of an OFDM-based WLAN transmitter in MATLAB that provides phase angle values to a CORDIC module. This CORDIC module is implemented using VHDL and analyzes the phase angles to compute sine and cosine functions. Simulation results show that the VHDL-implemented CORDIC produces the same output waveforms as MATLAB, validating the accuracy of the hardware implementation.
