Hierarchical Cellular Structures in High-Capacity Cellular Communication Systems

Hierarchical Cellular Structures in High-Capacity Cellular Communication Systems

In the prevailing cellular environment, it is important to provide the resources for the fluctuating traffic demand exactly in the place and at the time where and when they are needed. In this paper, we explored the ability of hierarchical cellular structures with inter layer reuse to increase the capacity of mobile communication network by applying total frequency hopping (T-FH) and adaptive f...

Secure Communication in Shotgun Cellular Systems

In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...

MIMO capacity in cellular systems

In this paper, we examine the performance of conventional MIMO schemes in cellular systems in terms of average capacity. We find that the performance behavior of using larger number of transmit antennas in cellular system can be different from that in an isolated system. And we propose theNumber-of-Trasnmit-Antenna Selection scheme for MIMO cellular systems.

Teletraffic Capacity Of Hierarchical CDMA Cellular Networks

Teletraffic analysis of hierarchical cellular communication networks

—The sustained increase of users and the request for advanced multimedia services are some of the key motivations for designing new high capacity cellular telecommunication systems. The proposals which are being pursued by several studies and field implementations consider hierarchical architectures and dynamic resource allocation. In this paper a hierarchical cellular communication network is ...
