ICI Performance Analysis for All Phase OFDM Systems

  title={ICI Performance Analysis for All Phase OFDM Systems},
  author={Renhua Ge and Shanlin Sun},
Orthogonal frequency division multiplexing (OFDM) is a strong candidate for the next generation wireless communication. But the frequency offset between the local oscillators at the transmitter and receiver causes a single frequency offset in the signal, while a time-varying channel can cause a spread of frequency offsets known as the Doppler spread. Frequency offsets ruin the orthogonal of OFDM sub-carriers and cause inter-carrier interference (ICI), therefore, quickly diminishing the… CONTINUE READING
