OFDM interference analysis in nonlinear time-varying radio channels with frequency offsets

Nonlinear distortions and frequency offsets are two major problems of OFDM transmission that essentially affect its reliability. In this paper, we analyze OFDM by taking into account both effects. For a wide-sense stationary uncorrelated scattering channel we derive an approximate analytical expression for the signal - to - total interference power ratio… CONTINUE READING
