Simulation of Smart Antenna System using ADS Co-Simulate with Matlab: Direction of Arrival estimation and Interference Canceller

In this paper, we present the computer simulation for adaptive antenna system to improve the signal-to-interference ratio by steering beam pattern to track the user signal while maintaining placing the null in the direction of interference signal by updating the weight coefficients using SQP algorithm. In Advanced Design System (ADS), the signal processing co-simulates with either circuit envelope or transient simulators. Antenna and propagation models simulate the effects of radio channel, including signal fading and path loss
