N2 - In this paper, we consider a two hop cognitive radio network where there are multiple primary and secondary users. We propose the design of antenna weights at the source and relay based on zero forcing principles. These antenna weights are designed to cancel the interference among the secondary users while maintaining fairness, and to ensure interference free signals at each primary user. To analyze the performance of our proposed design, we derive new exact expressions for the signal to interference and noise ratio at each secondary user, which are subsequently used to analyze the error performance.
