RAKE COMBINER DEVICE USING CHARGE TRANSFER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide high-accuracy RAKE reception equipment in simple configuration by previously estimating the multipath environment of a communication path and supplying a digital signal for determining the transfer route of each input charge signal to a charge routing mechanism. SOLUTION: This device is composed of the charge routing mechanism, signal storage mechanism and RAKE controller. The signal storage mechanism stores routed charge signals, and the RAKE controller previously estimates the multipath environment of the communication path related to the reception of input signals and supplies the digital signal for determining the transfer route of each input charge signal to the charge routing mechanism. Concerning such a device, an input IN is a charge packet stream outputted from a matched filter, a router R transfers each charge packet to the direction of '0' or '1' according to the value of the digital supplied from the RAKE controller and after the respective charge packets are cumulatively added for a prescribed period at buffers B0 and B1, the amount of accumulated charges is evaluated.
