Semi-sequential MIMO radio channel sounding
Razavi-Ghods, N; Salous, S
Abstract
Multiple antenna technologies have long been considered as a powerful tool for enhancing the performance of wireless systems. MIMO (multiple-input multiple-output) systems in particular, which exploit the rich scattering radio environment are being extensively studied because of their ability to provide significantly higher channel throughputs than conventional single antenna systems. The characterisation of such multi-antenna propagation channels is vital to the future development of MIMO technologies, Here we introduce a semi-sequential channel sounding scheme, which will provide both high-resolution delay/Doppler information and spatial information. The aim is to study the real-world propagation effects of frequency-selective time-selective channels. Measurement results are presented for several different antenna array geometries, using both linear and circular (sector) antenna arrays. Measurement results include delay/Doppler characteristics and channel capacity results for different indoor MIMO environments.
