Multipath Interference Cancellation in MIMO Mobile Cellular system

Abstract

Wireless network widely used today include, cellular network, wireless mesh network (WMNs), wireless local area network and personal area network.The increasing demand for these networks has turned spectrum into a precious resource.For this reason, there is always a need for methods to pack more bits/Hz.A particular solution is to use multiple antenna at both transmitter and receiver side.Such a system is called multiple-input multiple-output (MIMO) system.In real propagation environment of cellular communication, channel reuse will cause the co-channel interference which will degrade the MIMO channel performance.The interference cancellation (IC technology) can handle efficiently the cochannel interference.In this paper comparison computer simulation for zero forcing successive interference cancellation (ZF-SIC) minimum mean square error (MMSE equalizer) and maximum likelihood (ML) for two transmitting and two receiving antenna is shown.
