A signal processing method is provided for processing a plurality of input frequency domain data within a frequency band, each of the input frequency domain data having magnitude and phase characteristics and being associated with a phase parameter that corresponds to the phase characteristic thereof. The method includes: arranging the input frequency domain data in sequence on a variable axis; rearranging positions of the input frequency domain data on the variable axis with reference to at least the phase parameters of the input frequency domain data; and combining the rearranged input frequency domain data that are disposed on the same position on the variable axis to result in processed frequency domain data. The signal processing method can preserve and transmit phase characteristics at various frequencies, and is suitable for application to cochlear implant systems, retinal implant systems, and multi-phase data transmission systems.
