1. A receiver capable of enhancing receiving efficiency in a code division multiple access communication system comprising:
a signal reception end for receiving signals;
a data output unit for outputting a plurality of data streams corresponding to a plurality of codes according to signals received by the signal reception end;
a control unit for outputting a data stream having maximum signal power when an amount of the plurality of data streams is smaller than a first value;
a first multiplication unit for multiplying signals received by the signal reception end with the data stream outputted from the control unit;
a high pass filter unit for discarding a DC portion of signals outputted from the first multiplication unit; and
a second multiplication unit for multiplying the data stream outputted from the control unit with signals outputted from the high pass filtering unit and outputting a multiplied result to the signal reception end.
