In this paper the computational complexity associated with optimum maximum likelihood detector in wideband code division multiple access systems is addressed. In the proposed scheme, large number of users is divided in groups, each group having a unique orthogonal code and small number of users. Multiuser detection in a particular group is accomplished(More)
Target classification plays a vital role for outdoor security applications. The main focus of this paper is to describe a strategy to classify a target in a multi-channel seismic network. A technique of sensor level fusion is applied in a seismic network. This technique is based on correlation method. The method determines the weights of each seismic sensor(More)
