MULTI-POLARIZATION DIMENSIONALITY OF MULTI-ANTENNA SYSTEMS

Multi-polarization Dimensionality of Multi- Antenna Systems

Based on the deterministic Maxwellian framework, we investigate the ability of each of the dual fields (electric and magnetic) in carrying independent information in a multi-polarization MIMO system. We quantify the performance by using a well-defined power independent dimensionality (PID) metric. We present numerical results for 3 deterministic scenarios: a canonical free-space (near and far f...

Designing a Multiband Multi Polarization BTS Antenna

In this paper, a new antenna is presented which has an application in cellular telecommunication systems. The designed antenna works at the frequency range of 1900-2600 MHz which is able to cover 2G, 3G and 4G (LTE) services of the cellular telecommunication. In this paper, the micro-strip structure has been used to design the antenna. The shape of the patches is triangular where a peripheral r...

Multi - User Multi - Antenna Cooperative Cellular Systems

To meet the very high data rate requirements for wireless Internet and multimedia services, cooperative systems with multiple antennas have been proposed for future generation wireless systems. In this thesis, we focus on multiple antennas at the source, relay and destination. We study both downlink and uplink cooperative systems with single antenna relays. For downlink systems, the optimal pre...

Comparison of Multi-cell Multi-antenna Cdma and Tdma Systems

We evaluate system capacities for multicellular systems with different multiple access strategies. The interference from another cell sharing the same frequency is calculated, and the total interference arising from the frequency reuse pattern is evaluated. A simple analytical model for the inter-cell interference is developed, which is in good agreement with numerical experiments. Irrespective...
