Impact of the Base Station Antenna Beamwidth on Capacity in WCDMA Cellular Networks

In this paper the impact of the base station antenna horizontal beamwidth on radio network capacity in WCDMA cellular networks in the downlink direction is studied. Influence of coverage overlapping and radio propagation environment together with antenna beamwidth are also studied. A radio network planning tool is used to simulate WCDMA macro cellular network performance in urban and suburban a...

Design of a Magneto-Electric Dipole Antenna for FM Radio Broadcasting Base Station Antenna Implementation

This work presents the design of a magneto-electric dipole (MED) antenna for the base station antenna of FM radio broadcasting implementation. The advantages of MED antenna are high gain, stable and symmetrical radiation patterns in both electric and magnetic planes, and low back lobe radiation pattern. The antenna was designed and studied to achieve the optimal dimensions of configuration para...

Design of concatenated extended complementary sequences for inter-base station synchronization in WCDMA TDD mode

The Universal Mobile Telecommunications System (UMTS) being specified by the Third Generation Partnership Project (3GPP) and based upon Wideband Code Division Multiple Access (WCDMA) consists of a frequency division duplex (FDD) mode and a time division duplex (TDD) mode. In the UMTS Terrestrial Radio Access (UTRA) TDD mode, system capacity is maximized with base stations (Node B's) in a UTRA T...
