Double Reuse Digital Systems using Sectored Cells Yasuaki Kinoshita and David K. Asano Department of Information Engineering, Shinshu University, Nagano, Japan Abstract|To enhance frequency utilization e ciency, cellular mobile radio systems widely use a sector cell structure for the base stations. In this paper, the conceptual design formula previously reported are extended for frequency double reuse indoor picocellular systems. A three sector cell structure is adopted for the urban cellular base stations and omni-directional base stations are used for the indoor system, which is in the nal stage of implementation. In particular, the small cluster size case is analyzed for TDMA cellular systems.

Downlink Scheduling and Resource Management for Best Effort Service in TDD-OFDMA Cellular Networks

Throughput performance and geographical service fairness of best effort service used for downlink of a 802.16e based TDD-OFDMA sectored cellular networks are evaluated in conjunction with different scheduling schemes and frequency reuse plans. The OFDM systems are based on two multiple access schemes, which are the OFDM-TDM and OFDMA, and considered scheduling schemes are round robin, max C/I, ...

Channel alternation and rotation for tri-sectored directional antenna cellular systems

Due to discrete reuse cluster sizes, disjoined and uniformed channel assignment, conventional tri-sectored cellular systems have not taken full advantage of antenna directivities. In this paper, we present a novel Channel Alternation and Rotation (CAR) scheme to coordinate channel assignment with antenna directivities. In CAR, cell layout is based on two-tier cell-reuse structure and each cell ...

Variable Sectored Antenna Medium Access Control (V-SAMAC) Protocol for Wireless Sensor Networks

Wireless sensor networks have been used to gather data and information in different field applications. Different fields have different needs and requirements like some need high data rates, some need high throughput and some need less delays etc. In order to address these QoS requirements, we have used sectored antennas over the Omni-directional antennas. The most important benefits of using s...

Inter-sector Interference Mitigation Method in Triple-Sectored OFDMA Systems

In this paper, a network-centric subcarrier allocation method is proposed for triple-sectored Orthogonal Frequency Division Multiple Access (OFDMA) systems. The proposed method is based on a networkcentric algorithm that is located in a base station (BS) and coordinates the subchannel allocation of each sector. This method controls the resources (subchannels) allocated to each sector, not to wa...
