A Multilevel Soft Frequency Reuse Technique for Wireless Communication Systems

Design of a novel congestion-aware communication mechanism for wireless NoC architecture in multicore systems

Hybrid Wireless Network-on-Chip (WNoC) architecture is emerged as a scalable communication structure to mitigate the deficits of traditional NOC architecture for the future Multi-core systems. The hybrid WNoC architecture provides energy efficient, high data rate and flexible communications for NoC architectures. In these architectures, each wireless router is shared by a set of processing core...

A New Frequency Partitioning and Allocation of Subcarriers for Fractional Frequency Reuse in Mobile Communication Systems

Some OFDMA-based wireless commuication systems, e.g., Wireless Broadband Internet (WiBro) or Worldwide interoperability for Microwave Access (WiMAX), support frequency reuse of 1 to maximize spectral efficiency. One of the efficient methods to reduce co-channel interference (CCI) caused by frequency reuse is fractional frequency reuse (FFR). In this paper, we propose and validate a novel freque...

Throughput Analysis of Cooperative Communication in Wireless Ad Hoc Networks With Frequency Reuse

In this paper, we investigate the network throughput achieved by both spatial diversity and spatial frequency reuse in a wireless ad hoc network with randomly positioned single-hop source-destination pairs and relays. Compared to conventional direct transmissions, cooperative communication can enhance single-link transmission reliability, but reduce network-wide spatial frequency reuse due to r...

Infrastructure Density and Frequency Reuse for Wireless LAN Systems at 17 GHz in an Office Environment

Using Wireless LANs (WLANs) in offices is becoming increasingly popular and operators start now offering access to wireless services via WLANs also in public areas. WLANs operate mostly at 2.4 GHz or 5 GHz. Propagation properties at these frequencies require a relative high frequency reuse even for typical indoor environments, which limits their spectral efficiency. In the 17 GHz band, which is...
