We propose an unslotted CSMA with grouped sensing and analyze the throughput of SUs in multi-channel cognitive radio network. We model the system by 3-demensional continuous time Markov process, calculate the steady state probability of the system, and obtain throughput and transmission delay of SUs. By comparing the performances of grouped sensing scheme, random m-sensing and hybrid sensing, the numerical results show that grouped sening scheme overcome the defect of low throughput in random m-sensing scheme.
