RP-CDMA is a wireless multiple access technique that utilizes multiple spreading codes and a multiuser detector to enhance link reliability and performance. We propose a simple MAC protocol on top of the RP-CDMA Phy and apply it to the multihop ad hoc network model. In addition to a MAC, we...
A significant challenge for fourth generation cellular systems is the reliable delivery of high speed (up to 1 gigabit per second) data to mobile or nomadic users throughout a cluttered urban environment. The wireless channel is a difficult channel over which to achieve high rate reliable...
Reduced–Complexity Transmission and Reception Strategies in Coordinated Multi-cell Wireless NetworksDownload
Interference is known as a major obstacle for the spectral efficiency increase promised by multiple-antenna techniques in cellular wireless communications. Recently, it has been shown that multi-cell coordination can mitigate interference and improve system performance dramatically. Hence, we...
Synchronisation and Wavelet Compression for Background Interference Classification in Wireless EnvironmentsDownload
Dense wireless deployment environments are increasingly facing Radio Frequency (RF) spectrum congestion and increased levels of interference. Addressing the interference will require a distributed decision-making application on wireless nodes, that characterize the state of the channel with...
This thesis investigated the feasibility of using the Dedicated Short Range Communication (5.9 GHz) protocol as a vehicular wireless system for transmitting elderly drivers‘ vital signs in medical emergencies. Existing vehicular communication systems, physiological monitors, and low-power...
