Recent works have developed a simple and robust myopic sensing policy formulti-channel opportunistic communication systems where a secondary user (SU)can access one of N i.i.d. Markovian channels. The optimality of the myopicsensing policy in maximizing the SU's cumulated reward is established undercertain conditions on channel parameters. This paper studies the generic casewhere the SU can sense more than one channel each time. By characterizing themyopic sensing policy in this context, we establish analytically its optimalityfor certain system setting when the SU is allowed to sense two channels. In themore generic case, we construct counterexamples to show that the myopic sensingpolicy, despite its simple structure, is non-optimal.
