摘要：
Cyclic Prefix (CP) has been applied in the single-carrier systems to resist the inter-block interference (IBI) due to the frequency selective fading channel and equalize the channel by one-tap frequency domain equalizer. However, there still exists the residual inter-symbol interference (ISI) due to imperfect channel equalization, which will severely degrade the system performance. In this paper the residual ISI is analysis in CP-SC with linear minimum mean square error (LMMSE) equalizer. With the initial estimates of LMMSE equalizer, the interference cancellation (IC) technique is adopted to alleviate the residual ISI so that the system performance can be considerably improved.
