Abstract
A receiver comprising: an antenna which receives a radio signal including N possible symbols {c, c, . . . c, c}, an N correlation units which are provided corresponding to the N possible symbols, respectively, each correlation unit detecting the degree of correlation with the radio signal received by the antenna, and a symbol determination unit which determines the symbol included in the radio signal received by the antenna based on the degree of correlation detected by the N correlation units. The N correlation units detect the degree of correlation between the radio signal received by the antenna and the N possible symbols represented by M chips {αc, αc+αc, . . . , αc+αc, αc+αc}.
