Publication number: 20030083014Abstract: In accordance with the present invention, a method is provided for a mobile station to select one cell site in a plurality of cell sites in cellular systems with an Interference Free Window. This method is based on measurement of the signal on the downlink. In preferred embodiments, a mobile station receives the downlink spread spectrum signals from a plurality of neighboring cells. By using a RAKE type correlator or matched filter, the signal energy and the multipath delay spread profile can be estimated at the mobile station. A new function is defined as the ratio of the multipath delay spread to the energy of the received signal. Minimizing the said function will result in a cell site that provides the best quality of service in a multipath propagation environment.Type: ApplicationFiled: December 3, 2002Publication date: May 1, 2003Applicant: Linkair Communications, Inc.Inventors: Daoben Li, Haiyang Gao, Shiu Ming Joseph Ho, Yongsheng Zhang, Weidong Chen, Yuanhua Deng, Jianming Xu
