  In this paper, we propose clipping noise cancellation scheme using compressed
sensing (CS) for orthogonal frequency division multiplexing (OFDM) systems. In
the proposed scheme, only the data tones with high reliability are exploited in
reconstructing the clipping noise instead of the whole data tones. For
reconstructing the clipping noise using a fraction of the data tones at the
receiver, the CS technique is applied. The proposed scheme is also applicable
to interleaved orthogonal frequency division multiple access (OFDMA) systems
due to the decomposition of fast Fourier transform (FFT) structure. Numerical
analysis shows that the proposed scheme performs well for clipping noise
cancellation of both OFDM and OFDMA systems.
