The performance characteristics of the cell averaging (CA), greatest of (GO), and smallest of (SO) constant false alarm rate (CFAR) processors in homogeneous environment are analyzed and compared when receiving antenna diversity is employed in the pseudonoise code acquisition of direct sequence code division multiple access systems. From the simulation results, it is observed that the CA CFAR scheme has the best performance and the GO CFAR scheme has almost the same performance as the CA CFAR scheme in homogeneous environment.
