It has been confirmed also by measurements that in rich scattering environments an antenna spacing below 0.5 lambda is sufficient to reach nearly the full capacity predicted for multiple-antenna arrays in ideal and uncorrelated Rayleigh fading channels.enantenna arraysantenna testingchannel capacityelectromagnetic wave scatteringindoor radiomimo systemsray tracingrayleigh channelsreceiving antennastransmitting antennasantenna spacingmimo channelsindoor environmentsray tracing programrich scattering environmentsantenna measurementsmultiple-antenna arraysideal uncorrelated channelsrayleigh fading channelsmultiple-element antenna arrays621conference paper
