Abstract
The invention relates to a method of performing code acquisition on a signal to be received and to a receiver implementing the method. In the method the receiver receives a signal from a transmitter by at least two antenna beams, and to perform code acquisition, the antenna beams formed are searched at different delays of the spreading code. The number M of antenna beams can also be changed adaptively by determining a signal-to-noise ratio and by forming a number of antenna beams which is proportional to the signal-to-noise ratio. The receiver performs code acquisition by receiving a signal from the transmitter and by searching the antenna beams formed at the different delays of the spreading code.
