The Simulation Research Of Smart Antenna System

With the rapid development of the world communication service, wireless mobilecommunication technology regarded as future personal communication main means makes us paymuch attention to. How to eliminate the CCJ, MA! and multipath fading becomes the essentialfactors conside~d when ~ve impmve the system perfomiance of wireless mobile communication.Smart antennas use the digital signal pmcessing technologies to pmduce spatial and directionalbeam, then let the antenna's main beam point to the coming direction of reference user and the sidelobe point to the coming direction of interference user. Compared with other mature interferenceelimination technologies, the application of smart antenna technology in mobile communicationshows its tremendous potential.The main contents in this paper are:1. Summarize the pmgress of the mobile communication system and some technologies ofthe Thin! Generation Mobile Communication System.2. Create the practical wireless time-space channel model and consider the condition of timedelay spre4 angle spre4 Doppler fi~quency spread and rayleigh fading.3.Desciibe the piinciple of several adaptive algorithms, including: cascade algorithm,cascade+DR algorithm, code fflter algorithm and constant modulus algorithm4.Accoiding to the time-space channel model, compare the simulation outcomes of severaladaptive algorithms and analyze their outcomes.5.Acconiplish the experiment flat of Smart Antenna system simulation preliminamy...
