Receiver with adaptive antenna array

摘要

A mobile communication system receives a despread signal of a reception signal, and performs a control operation such that a weight for generating a reception beam is calculated using a first technique if a difference between an error value at a current time and an error value at a previous time is greater than an absolute value of a first threshold or the error value at the current time is greater than or equal to a second threshold, and performs a control operation such that the weight is calculated using a second technique if the different between the error value at the current time and the error value at the previous time is less than or equal to the absolute value of the first threshold and the error value at the current time is less than the second threshold.
