This paper addresses the problem of locating and tracking a low-power beacon signal in an adverse, multipath environment. We present an implementation scheme for a wideband transmission and direction finding system. This approach takes advantage of delay discrimination to improve angle-of-arrival (AOA) estimation in a multipath channel with high levels of additive white Gaussian noise. Frequency offset estimation is complicated by the poor signal to noise ratio (SNR) and represents the most significant challenge for effective operation. The simulation improves the performance of OFDM signal by mitigating the effect of frequency offset synchronization to give error free data at receiver, good angle of arrival accuracy and improved SNR performance.
