The Secondary Users¡¦Throughput Maximization in Cognitive Radio System Under Channel Capacity Constraint

In a CR network, the maximum SUs throughput is desired generally. In this thesis, We
investigate and formulate the problem of the secondary users¡¦ throughput maximization in
cognitive radio systems under channel capacity constrain. By using KKT theorem, an objec-
tive function is developed to obtain an optimal solution for the SU throughput maximization
problem. An numerical example is also presented for illustration. The most important results
revealed in the example show that the maximum SU throughput is achieved by cooperating an
optimal number of SU pairs instead of cooperating all the SU pairs.
