Effective radiation pattern concept for wireless systems analysis
In this Letter, the use of the effective radiation pattern (ERP) concept for wireless systems analysis is proposed, in order to account for multipath angular spread effects upon ideal antenna radiation patterns. The method for producing the ERP that optimally models any real antenna radiation pattern is presented and the proof of concept is demonstrated via large-scale simulations for a multicellular beamforming system. Results show that the accuracy in SIR calculations is better than 1 dB.
