Experimental Evaluation of Interference Alignment for Broadband WLAN Systems
n this paper we present an experimental study on the performance of spatial Interference Alignment (IA) in indoor wireless local area network scenarios that use Orthogonal Frequency Division Multiplexing (OFDM) according to the physical-layer specifications of the IEEE 802.11a standard. Experiments have been carried out using a wireless network testbed capable of implementing a 3-user MIMO inte...
متن کاملExperimental Evaluation of Coexistence Method for ZigBee under WLAN Interference
—ZigBee has attracted attention for constructing the sensor network such as home energy management system. Both ZigBee and wireless LAN (WLAN) use a 2.4GHz band, called the industrial, scientific, and medical unlicensed band; therefore, ZigBee faces severe interference problems in the presence of WLAN. Frame collisions are serious problems between ZigBee and WLAN. Both employ a carrier sense m...
متن کاملInterference Mitigation Techniques for Broadband Satellite Systems
This paper presents an overview of possible interference mitigation techniques aiming at increasing the system capacity of broadband multimedia satellite systems. A multi-star network topology using a bent-pipe transparent satellite is assumed. After a general overview, the paper concentrates on the assessment of Linear Precoding techniques for increasing the potential system capacity on the Fo...
متن کاملInterference Alignment for UWB-MIMO Communication Systems
Due to the enormous occupied bandwidth even by a single pair of UWB users, one major scientific challenge in UWB communications is interference management. Recently, Interference Alignment (IA) has become popular not only to well manage the interference, but also to optimally exploit the possible capacity gain caused by multiple pairs of transmitters and receivers. Theoretically, IA scales the ...
متن کاملEffect of Fragmentation in WLAN Systems with Interference Problems
Results from simulation model of an 802.11 WLAN system that suffers in performance due to interference problems are presented. The effect on performance due to change in fragmentation thresholds are shown in terms of traffic sent, received, and retransmission attempts with and without RTS/CTS mechanism. It is shown that for the modeled system a fragmentation threshold value of 256 to 500 octets...
