Abstract
The frequency shifts created by the imperfections of local oscillators and the Doppler-effect generating inter-carrier interference responsible for the degradation of system performance. Several studies have been developed to reduce this interference. A comparative study of different methods facilitates the choice of the most appropriate algorithm. Our study investigates and compares two algorithms, the ICI Self Cancellation and Symmetric Symbol Repetition. In terms of CIR, it appears that the method of Symmetric Symbol Repetition offers better performance; however, these same performances degrade rapidly when the carrier offset frequency increases. In terms of performance stability, the ICI Self Cancellation is most appropriate.
