Executive Summary

Multi-Input Multi-Output (MIMO) receivers have been designed and their communication performance analyzed under the assumption of additive Gaussian noise. Wireless transceivers, however, may be affected by Radio Frequency Interference (RFI) that is well modeled using non-Gaussian impulsive statistics. In this paper, the authors consider the problem of receiver design for a two transmit, two receive antenna MIMO system in the presence of RFI. First, they show that RFI is well modeled using a bivariate Middleton Class A model and validate the model with measured data. Using this RFI model, they describe that conventional MIMO receivers experience significant degradation in communication performance.
