Subscriber Maximization in CDMA Cellular Networks
نویسنده
چکیده
We calculate the maximum number of subscribers in a CDMA cellular network for a given GoS requirement, QoS requirement, network topology, and user distribution profile. We formulate a constrained optimization problem that maximizes the call arrival rates subject to upper bounds on the blocking probabilities and lower bounds on the bit energy to interference ratios. We present examples for traditional and optimized network topologies with uniform and non-uniform user distribution profiles and different mobility scenarios.

Subscriber Location in CDMA Cellular Networks
Subscriber radio location techniques are investigated for code-division multiple-access (CDMA) cellular networks. Two methods are considered for radio location: measured times of arrival (ToA) and angles of arrival (AoA). The ToA measurements are obtained from the code tracking loop in the CDMA receiver, and the AoA measurements at a base station (BS) are assumed to be made with an antenna arra...

متن کاملSecurity Enhancement Using Mutual Authentication in Existing CDMA Systems
Even though CDMA2000 wireless networks are being widely deployed as a cellular digital standard around the world, it has some hidden vulnerabilities concerned with security issues. The existing CDMA systems use authentication mechanism by CAVE (Cellular Authentication and Voice Encryption) algorithm. This authentication method has several disadvantages. Only one way authentication is provided, ...
متن کاملHybrid Cellular/WLAN Networks with Wireless Offloading: A Novel Communication Paradigm
The exploitation of already deployed wireless local area networks (WLAN)s (e.g., WiFi access points (AP)s) has attracted considerable attention, as an efficient and practical method to improve the performance of wireless networks. In this paper, we propose a novel communication paradigm to satisfy the performance demands of the future wireless networks: a hybrid Cellular-WLAN network architectu...
متن کاملPerformance Analysis of a Cdma Wireless Local Loop Systems
In this paper, the capacity of the Code Division Multiple Access Wireless Local Loop (CDMA WLL) system is analytically derived, and the capacity gain achieved in a CDMA WLL over a cellular mobile environment is calculated. The results show that the CDMA WLL system can support up to 36 % more users than CDMA cellular mobile system. The paper also propose a new approach to increase the reverse li...
