| Abstract: | To solve the inter carrier interference(ICI) elimination problem of an M-band wavelet multi-carrier modulation system,this paper analyzes the principle of the ICI caused by the Doppler frequency shift and its mathematical expression based on the M-band wavelet multi-carrier modulation system model.Through the analysis of the mathematical expression and combining with the perfect reconstruction conditions of the filter banks,we propose the design conditions of an M-band filter to reduce and eliminate the ICI... |
