Partially overlapping tones have recently been offered as a new solution to reduce the other user interference in cognitive heterogeneous networks. By introducing intentional carrier frequency shift, the users can exploit the gaps between the subcarriers. In this letter, we perform game theoretical resource allocation with partially overlapping filtered multitone signaling. To achieve the resource allocation, a secondary base station slides a group of consecutive subcarriers through all available ones and computes the utility for each selected subcarriers. It picks the consecutive ones, which give the highest capacity result. By performing this scheme, the other user interference is reduced significantly with a slightly slower convergence rate.
