Abstract:
A spectrum spreading communication system including a radio base station comprising:a receiving section for receiving a radio signal to produce a digital burst signal, wherein transmission data of the radio signal respectively include different pilot patterns and data, are subjected to spectrum spreading using a single spreading code, and are transmitted on a same frequency band; a correlation detecting section for performing a tracking operation to said burst signal for each of paths to produce a tracking resultant data, said paths being specified based on a path data, and detecting a component of said burst signal correlated with said spreading code for each path based on said tracking resultant data; a rake synthesizing section for performing rake synthesis to said components from said correlation detecting section for each of said pilot patterns; and a control section for determining path candidates from said burst signal to output said path data corresponding to said path candidates to said correlation detecting section, and for controlling said rake synthesizing section to perform said rake synthesis to said components from said correlation detecting section for each of said pilot patterns.
