Tracking of a multi-path resolved signal in a rake receiver

Abstract

Multi-path of the device for resolution is appointed edges of the spread spectrum Rake Rake receiver. Device for resolution of a delaying. The variable time delay the device for resolution, operating early of late detection, so that the number of determining of the resolution the shift device is an earlier time to the best arrival time or lags to firmly. And the early of late detecting by the resolution the device to transfer to an earlier time support part, and a first pulse. And the early of late detecting by the hysteresis device of resolution support part, and a a second pulse. First and second pulse is counted. The first pulse driving according to the first direction counting, and a second pulse driving according to the second direction counting. From the counting value disposed, a digital sheet time delay timing adjusting signal, and the feedback to which is used to adjust the resolution the component a delaying. Derivation sheet for time delay phase conditioner signal from the counting value; and the feedback to which is used to control the pseudo noise phase generator.
