Throughput maximization problem is considered in this paper.Here, throughput analysis is done for fixed allocation of channels.Fixed allocation of channels means number of primary users allocated to a channel is considered to be fixed but the number of users is different for different channels.Primary users allocated to a specific channel compete to access the channel and the cognitive users sense the channel whether the channel is free or not.The transmission probabilities of primary and secondary users are different.In this paper we consider the delay related to channel access of secondary users.We consider number of secondary users is very large.Our objective is to find the optimal number of secondary users to maximize the total throughput of primary and secondary users.
