This paper presents a receiver antenna synchronization and carrier frequency offsets pre-mitigation procedure, which is proposed for distributed massive MIMO system. The technique's performance is dependent to the SNR as well as the number of OFDM symbols per transmission packet. It has been shown that the procedure is working using a rapid prototyping platform based on WARP board. The MIMO system...
Scheduling technique plays a significant role in distributions of Resource Blocks (RBs) in LTE system. In order to ensure the LTE system operates efficiently, the scheduler needs a good trade-off between the overall cell throughput and the fairness to all the users' equipment (UEs) in its respective cell. Improving the overall cell throughput while maintaining its fairness level is very crucial in...
The next generation, 5G wireless access, is going to support a wide range of new applications and use cases, with the capabilities including very high achievable data rate, very low latency, ultra-high reliability and the possibility to handle extreme device densities. To avoid the costly deployment, operation and maintenance of future mobile network, Radio Access Network (RAN) virtualization or Cloud...

Long Term Evolution (LTE) packet scheduler is a key mechanism in the LTE traffic handling. It is mainly in charge of allocating physical resource blocks for the attached UEs. The main problem in LTE scheduler is to maximize the throughput while maintaining the fairness. The performance of scheduler is very critical, especially when many UEs are located at the cell edge. The new proposed scheduler...
Active service discovery in 802.11 requires the WLAN clients to broadcast the probe request frame based on its' list of preferred networks while searching for Access Point (AP) prior to authentication and association. The Medium Access Control (MAC) address, a unique identifier allocated to a network interface, is embedded in the probe request frame. Coupling with his or her personally identifiable...
To avoid interference from a detected radar signal, or to reassign mesh station (STA) channels to ensure the connectivity, IEEE 802.11s defines a procedure on how to propagate the channel switch attempt throughout the mesh network, known as mesh Basic Service Set (MBSS) channel switch. Wireless Mesh Network (WMN) that utilizes single-radio nodes with omni-directional and directional antennas is ideally...
Commercial solution for 802.11n has been made available in the market for quite some time. It is steadily gaining popularity due to its promise of maximum physical (PHY) data rate up to 600 Mbps. However, the 802.11n firmware is not publicly available compared to the 802.11a/b/g firmware. Thus, we hardly found any experimental study on 802.11n from the wireless local area network (WLAN) research community...
IEEE 802.11n standard has fulfilled the promise of improved performance when compared to the previous generation of Wireless Local Area Networks (WLANs) with the possibility of physical transmission rate up to 600 Mbps. But the well known performance anomaly of 802.11 still remains an open issue. A mobile station tends to change its modulation and coding scheme and transmit at lower bit rate due to...
Reconfigurable embedded system provides a flexible platform for hardware circuit implementation. Embedded systems often come with stringent performance and power requirements, leading the designers to incorporate special purpose hardware accelerator into their design. Furthermore, the tight timing requirement for the software design can be met using real time operating system. In this paper, we have...
