Analysis of PCC-OFDM systems for general time-varying channel
IEEE Communications Letters（2005）
摘要
In this letter, we derive the general expression of ICI power for 1/2 rate PCC-OFDM system in terms of the correlation function of the channel. We have also developed the upper and lower bound of 1/2 rate PCC OFDM system and found that the ICI power reduction due to coding is about 11.9 dB. To examine the validity of the general expressions, we consider the example of carrier frequency offset (CFO), 2-path, Jakes' and uniform Doppler spread channel models and show that the results are consistent with simulations.
