A communication apparatus, a method, and a tangible machine-readable medium thereof for processing ranging interference of an orthogonal frequency division multiplexing (OFDM) signal. The communication apparatus comprises a receiving unit, a processing unit, and a mask generating unit. The receiving unit receives the OFDM signal having a plurality of OFDM symbols. The processing unit estimates a delay value and an energy value of at least one ranging code according to the OFDM symbols. The mask generating unit generates a mask function according to the delay value and the energy value. Finally, the processing unit synthesizes the ranging interference in the OFDM signal and removes it according to the mask function.
