Abstract:
1. A base station for receiving a transmitted signal from a mobile device, comprising: a master processing unit; a first processing unit connected with the master processing unit, comprising: a plurality of first rake receivers for receiving the transmitted signal; and a first detecting unit for receiving the transmitted signal and outputting a first detection signal; and a second processing unit connected with the master processing unit, comprising: a plurality of second rake receivers for receiving the transmitted signal; and a second detecting unit for receiving the transmitted signal and outputting a second detection signal, the quality of the first detection signal being larger than the quality of the second detection signal; wherein the master processing unit estimates a signature appropriate number (SAN) of rake receivers for receiving the transmitted signal according to the qualities of the first detection signals and the second detection signal and assigns the transmitted signal received by the second rake receivers when there are not enough first rake receivers in the first processing unit.
