Disclosed is a receiver capable of simplifying hardware required for finger and combiner in accordance with the channel characteristics in a 3generation mobile communication system using physical channels recommended by the 3GPP (3generation partnership project). The rake receiver for the mobile communication system complying with the 3GPP standard includes fingers for performing in parallel a radio signaling of downlink physical channels recommended in the 3GPP standard and inputted through multiple paths in a first-in first-out (FIFO) manner, combiners for summing a certain channel of different time offsets outputted from the fingers with an identical timing, and a selector for controlling the different physical channels outputted from the fingers to be summed by the different combiners, respectively.

Receiver for mobile communication system

Apparatus and method for determining a fixed point in a mobile communication system are disclosed. An initial fixed point is set through simulation and a saturation for an output of a target device is compared with a reference saturation. Then, the position of the initial fixed point is adaptively changed according to the change in the output range of the target device. Therefore, when a floating point is converted into a fixed point, the performance of the system can be improved while the complexity of the hardware can be reduced.
