| With the rapid growth of communication systems, utilization rate assessment turns to be of great importance for manage departments to allocate resources more effectively. In this paper, a blind detection algorithm of Wideband Code Division Multiple Access (WCDMA) channelization code is proposed. The algorithm is put forward to evaluate the spectrum of WCDMA network from a noncooperative perspective without the operator data. Since the code for Traffic channels is assigned by RNC, and is not fixed, management department cannot get the code table easily without the operator data. However, this paper only cares about the channel codes numbers, and does not care about the data they conduct. An algorithm of blind detection of channelization code is particularly put forward to evaluate the code utilization rate. And it is proved that the algorithm gets a high correct rate at low Signal Noise Ratio (SNR) through simulation |
