Interference in Mobile Cellular Cdma Forward Traffic Channels
نویسندگان
چکیده
Mobile cellular CDMA networks for tactical applications require mobile base stations in order to provide communications on the moue. Because of the mobility of the base stations, power balancing among the transmitters at different base stations is more dificult than in commercial cellular CDMA systems. Handoff of mobiles among base stations is also more difficult, primarily due to the mobility and the resulting lack of a high-speed wire-line network to interconnect the base stations. One important consequence is a higher likelihood of strong interference in the mobile receivers due to transmissions from neighboring base stations. In this paper the sensitivity to interference from neighboring base stations is investigated for the forward channels of a mobile cellular CDMA network.

Optimal Combining for Rake Reception in Mobile Cellular CDMA Forward Links
A bsiract— Two methods for mult ipath combining are compared for rake reception of a CDMA cellular forward-link traffic channel. Combining based on estimation of the signal-to-interference ratio of the output of each tap of the rake receiver is shown to provide significant performance improvement in comparison with the more commonly considered combiner that is based on measurement of the signal...
متن کاملBit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملLocation-Dependent Other-Cell Interference and Its Effect on the Uplink Capacity of a Cellular CDMA System
We consider the other-cell interference evaluation problem in a multi-cell CDMA system by looking at its location-dependence on the location distributions of mobile users in the cells. The goal is to characterize the location-dependent availability of radio resources in CDMA cellular networks. We model the locations of mobile users in a CDMA cell statistically by assuming certain location proba...

In CDMA mobile cellular systems, wireless quality is improved by soft handoff techniques. However, it requires to hold multiple channels of cells, which is likely to increase call blocking at wired channels. It is therefore necessary to consider the entire system including the wired and wireless portions of systems for investigating an effectiveness of the soft handoff. In this paper, we also c...
