In this paper, we develop an eavesdropping method for uplink wideband code division multiple access (WCDMA) system. In order to achieve effective eavesdropping of uplink WCDMA message, one of the most demanding systematic characteristics is the scrambling code information. While the previous works of identifying the scrambling code use only one antenna and cannot operate in practical environments, we propose an improved method for robust identification performance in more practical scenarios by using multiple antennas. The proposed method exploits not only multiple antennas but also non-coherent combining (NCC) which enables combining the received signals of each antenna without any channel state information (CSI). Through numerical simulation, we demonstrate that our method is effective for both slow and fast fading environments and evaluates the performance for various system parameters.
