Open-loop Power Control in CDMA Overlay,power control error in the presence of narrowband interference are analyzed and numerically computed. In order to get a minimum power control error in the CDMA overlay situations, an optimum downlink power allocation scheme is used, which works well for wide range of signal to narrowband interference ratio.

Book 2001in which further research is needed. As a background, I presume that the reader has a thorough understanding of digital communications and spread spectrum/CDMA. The book is arranged into 13 chapters. In chapter 1, some key specifications of 3G WCDMA are described and discussed. These techniques incl

Wideband CDMA,general multipath-fading channel model is assumed. A dedicated pilot channel, which is separate from data channels, is used for the purpose of channel estimation. Based on a digital implementation, the coherent demodulation scheme is presented. Pilot channel estimation error due to multiple access a

Multicode CDMA,annelization codes to any given user. If these channel codes are orthogonal, the self-interference among them can be eliminated in an AWGN channel. However, in a multipath environment, these intra-user signals from different delay paths no longer maintain orthogonality and thus cause interference, i

CDMA Overlay, wireless LAN applications. A suppression filter at a receiver is employed to reduce the narrowband interference. The average up-link bit error rate (BER) performance is investigated how to be influenced by various parameters, such as the number of taps of the suppression filter, the number of multi
