This paper studies multiple relay selection scheme in cognitive relay network to maximize the signal-to-noise ratio (SNR) of the secondary receiver. We first formulate the relay selection problem as a 0-1 integral programming problem, then propose an iterative relay selection scheme, which is suboptimal but simple. Numerical results indicate that the proposed iterative scheme can always achieve the near-optimal SNR performance.
