Abstract
The present invention provides a code division multiple access receiver which can maintain the accuracy of the result of demodulation of a received signal at a good level without increasing the scale of circuits and the amount of computation. In the code division multiple access receiver, a control sectionoutputs amplitude-adjusting signals corresponding to the reception level of a received base band signal to an amplitude-adjusting sectionand the amplitude-adjusting sectionperforms bit operation processes for removing invalid bit data from the complex correlation results of the received base band signal based on the amplitude-adjusting signals.
