A solution of f-OFDM system ISI based on ICI self-deletion technology

The invention discloses a solution of f-OFDM system ISI based on ICI self-deletion technology. The solution comprises the following steps: an ICI self-deletion encoding module is arranged between a sub-carrier mapping module and an IFFT module at the transmitting end; an ICI self-deletion decoding module is arranged between the sub-carrier demapping module and the FFT module at the receiving end;and an ICI self-deletion decoding module is arranged between the sub-carrier mapping module and the IFFT module. The ICI self-deleting coding module is used for modulating each data symbol output by the sub-carrier mapping module onto a group of adjacent L sub-carriers by adopting a set weight value respectively; The ICI self-deletion decoding module is used for linearly combining the data belonging to the same sub-carrier group in the data output from the FFT module according to a set weight value, wherein the weight value used in the combination corresponds to the weight value used by the transmitting terminal.
