Abstract
A transmitter 100 comprises a signal distributor 101 for outputting a modulation signal and a selection signal, a code generator 102 for generating a spread code, spread devices 103a to 103d for multiplying the spread code by the modulation signal and a selector 104 for selecting the modulation signal based on the selection signal. A receiver 110 comprises a correlator 112 for taking a correlation between the spread code multiplied by the reception signal and the spread code at a timing of the code generator 102, an equalizer 113 for removing a delay from the signal based on the correlation result, a signal location detector 114 for detecting the location of the signal output by the equalizer 113, a demodulator 115 for demodulating the signal output by the equalizer 113 and a coupler 116 for coupling the signal location information detected by the signal location detector 114 with the signal output by the demodulator 115.
