The advantages of Multiple Input-Multiple Output (MIMO) wireless communication systems are known for more than a decade. The operational mechanism of a 2 × 2 MIMO system generally reminds either having cross-polarised receiver/transmitter multiport antennas in line-of-sight (LOS), or both co/cross-polarised multiport antennas in non-line-of-sight multipath environments [1]. In contrast to the aforementioned...
Radiating cables (also known as leaky feeders) are often used to provide radio propagation in indoor and confined environments such as train passenger cars, aircraft cabins, subways or tunnels. Radiating cable deployments can typically provide more homogeneous and predictable coverage than deployments based on antennas. With the advent of 3GPP Long Term Evolution (LTE) and the IEEE 802.11n and 802...
A GPS aided inertial navigation platform is presented, into which further sensors such as a camera, wheel-speed encoder etc., can be incorporated. The construction of the platform is described and an introduction to the sensor fusion approach is given. Results from a field-test is presented, indicating which error sources that needs to be modelled more accurately
