<p>The receiver for code division radio interface (CDMA - Code Division Multiple Access) works on the signal received from a mobile network terminal and converted into baseband, where the group of digital signals obtained represents the sum of all the signals and the codes relating to the users that are transmitting at that moment on the frequency band assigned to the service. The information destined for each user is extracted by correlating the group of digital signals received with the user's code. The receiver can be designed as an integrated circuit library cell and, as such, gives a high degree of flexibility that permits it to be integrated in various terminals.</p> |
