Performance Analysis Of OSTBC In An Interference-limitedMIMO System

The communication quality of users is affected by CCI, especially the edge usersin an interference-limited environment.Orthogonal Space-Time Block Coding(OSTBC), as one of the most basic and promising coding methods, has a good abilityto combat fading and robustness to CCI.This paper mainly discusses the performanceof OSTBC in an interference-limited environment. The main points in this paper are asfollows:Firstly, there are several mathematical supposes in the past study on the statisticalproperties of co-channel interference when the destination channel and interferencechannel are both Raleigh fading. This paper solves them perfectly.Secondly, the channels are assumed static in the past study, but the channels aretime-varying in reality. So when the channels are time-varying, the statisticalpropertiesof CCI in a MIMO system with2transmit-antennas and1receive-antenna are studiedin this paper.Thirdly, the statisticalproperties of CCI in a MIMO system when the destinationchannels are Rice fading and the interference channels are Raleigh fading is studied.Finally, theoretical analysis has been verified through Monte-Carlo simulation.
