Measurement and Identification of Mobile Radio Propagation Channels
نویسندگان
چکیده
MIMO vector radio channel sounding devices allow multidimensional analysis of wave propagation in mobile radio channels. 6-dimensions represent Doppler, TDOA, 2-D DOD and 2-D DOA. Antenna array architectures, calibration and K-D unitary ESPRIT parameter estimation are discussed. Parametric channel models can be derived from the estimated data.

MIMO Measurement and Joint M-D Parameter Estimation of Mobile Radio Channels
We describe a measurement and parameter identification procedure for the mobile radio propagation channel which includes the azimuth directions of the propagating waves at both link ends, elevation at the base station, time delay, and Doppler shift. The measurement is based on a broadband, real-time multiple-input-multiple-output radio channel sounder. At the mobile station a circular uniform b...

With the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. Many site-specific methods have been proposed for modeling indoor radio channels. Among these methods, the ray tracing algorithm and the finite-difference time domain (FDTD) method are the most popular ones. The ray tracing approach ...

متن کاملPropagation Prediction Model for Land Mobile Communication in Microcellular Environment
The propagation channel is the principal contributor to many of the problems and limitations that degrades the performance of mobile radio systems. One obvious example is multipath propagation which is a major characteristic of the mobile radio channels, which severely affects the performance of digital systems by reducing the carrier-to-interference ratio. Thus accurate characterization of the...
