Abstract
This thesis presents the investigation of inter-carrier interference (ICI) in correlatively coded orthogonal frequency-division multiplexing (OFDM) communication system. First of all, we establish the mathematical model of the ICI problem individually for CP-OFDM and ZP-OFDM, which are the correlatively coded OFDM signals with cyclic prefix and with zero padding, respectively. Then we will take the average and minimum carrier-to-interference radio (CIR) respect to normalized frequency offset as two major indicators when measuring the ICI problem. Secondly, the data-conjugate method of ICI self-cancellation is studied to reduce ICI effectively and the system performance of the data-conjugate method is compared with the normal OFDM. Finally, we will make a comparison between the systems which we have discussed above in different system parameters in the conclusion chapter.
