中文摘要	Based on a Markov PU-occupancy model, an effective multi-channel access scheme was developed to improve the sharing of the spectrum between secondary users and primary users without interfering with the primary users and to optimize the spectrum use. The channel single secondary user occupancy and the sensing period have the most significant effect on the goodput. The theoretical optimal goodput is deduced, and it is confirmed by simulations. The goodput curve characteristics are then analyzed. The conclusion is shown that the goodput increases at first and decreases then as the channel single secondary user occupancy and the sensing period increase.
