Abstract

In this work, the adverse effects of a partial band jammer on a multi-user, multi-input multi-output cognitive radio networks are analyzed. In the proposed model, primary user transmits its information to the receiver with the aid of linear interference alignment method which uses a precoder and an interference suppression matrix. In this network, it is assumed that a partial band jammer adversely affects the transmission quality of the primary network. The analysis starts with the derivation of end-to-end signal to jammer noise ratio. Then, with the aid of probability density function and cumulative distribution functions, symbol error probability and outage probability are derived.
