This paper presents methods for synchronization in the downlink of a UMTS/TDD system. Space-time processing based on multiple receive antennas is used to suppress potentially strong co-channel interference caused by other base stations. We develop a detection-based synchronization procedure exploiting the structure of UMTS/TDD, and we present three alternative detection algorithms. Simulation r...

In this paper, we propose a new adaptive algorithm for generalized eigen-decomposition problems which plays very important roles in signal processing for wireless communication. We apply the algorithm to solve the problem of co-channel interference cancellation in Orthogonal Frequency Division Multiplexing (OFDM) communication system with virtual carriers. Finally, the simulations are performed...

Multi-Radio Multi-Channel Wireless mesh networks (MRMC WMNs) is the self-configuring backhaul providing internet access for last mile users through multi-hop forwarding. The increasing demand for low cost wireless networks coverage has motivated a high interest in multi-hop communications based recent and significant IEEE 802.11s WMN standard. One of the main challenges being faced by WMN is co...

In this study, a distributed scheme based on the Nash bargaining model is designed to coordinate co-channel interference for small-cell networks. The authors consider a scenario that resource blocks can be reused among different small cells. Different to existing works where resource allocation is conducted at the base stations, they propose the scheme where user initialises resource bargaining...

The heterogeneous network, contains a macro cell and a grid of low power nodes with the same frequencies, can improve the system capacity and spectrum efficiency. Configuring low-power nodes that share the same spectrum with macro cell to form heterogeneous networks makes it more likely to improve the system capacity and spectrum efficiency, but inevitably, strong co-channel interference is the...

There are many recent interests on cooperative communication (CC) in wireless networks. Despite the large capacity gain of CC in small wireless networks, CC can result in severe interference in large networks and even degraded throughput. The aim of this chapter is to concurrently exploit multi-radio and multi-channel (MRMC) and CC technique to combat co-channel interference and improve the per...

In this paper interference management in co-channel deployment of macrocell and cognitive femtocells is investigated. For the purpose of the aggregate interference mitigation from all femtocell access points (FAP) to macrocell user equipment (MUE) and the purpose to increase the radio link quality of femtocell system, a parameter named interference tolerable threshold (Ith) is introduced, the a...

In this paper, we investigate the performance of a decoupled space-time processing technique in a TDMA cellular system. This structure has, as its main characteristic, the possibility of giving more degrees of freedom to an antenna array, and it can thereby provide better co-channel interference cancellation. We analyze its performance by link-level simulations and its sensitivity for parameter...
