PROBLEM TO BE SOLVED: To receive a signal high in quality without mistaking an interference wave for a desired wave even when the autocorrelation characteristic of the desired wave in not remarkable. SOLUTION: After multiplying spread codes used on a transmission side by an inverse spreading equipment 9 and correlating them by means of a correlating equipment 10, a comparator 12 compares them with a threshold value. Then by setting some waves of large correlating values over the threshold value to be the candidates of the desired wave, selecting some waves of large correlating values over the threshold value 1 by means of a selector, or selecting some waves of large correlating values and then comparing them with the threshold value, signal components addressed to oneself is separated, and then decoded by a decoder 11 to obtain received data. |
