Interference cancellation in wireless communications using smart antennas

Abstract

We just consider the way to reduce the interference, from theory there are a lot of ways to do, however, we consider the smart antennas technique based on the two following algorithms in the thesis, that are: • LMS: Used to detect the unstable or slowly moving user. • LCMV: Used for stable or deterministic user. We will construct Matlab codes to describe “How do Smart Antenna Systems work?” and show how the noise and interference are canceled by these algorithms on the wireless communication channel. We also simulate by using Matlab program to demonstrate the affection of these algorithms in reducing interference. According to the simulation result, the problem in decreasing interference is solved by using LCMV and LMS, these methods are applicable and efficient.
