Abstract
In this paper, we propose a multiuser interference cancellation scheme for orthogonal frequency division multiple access (OFDMA) uplink systems. In the scheme, two steps of compensation and cancellation in time and frequency domains, respectively, are applied. In the frequency domain, we only consider the interference from both adjacent sides of the band to reduce the computation complexity and parallel interference cancellation is employed. Simulation results demonstrate that the proposed method reveals improved performance.
