—In this paper, a generic and adaptive geometry-based stochastic model (GBSM) is proposed for non-isotropic multiple-input multiple-output (MIMO) mobile-to-mobile (M2M) Ricean fading channels. The proposed model employs a combined two-ring model and ellipse model, where the received signal is constructed as a sum of the line-of-sight, single-, and(More)
For the practical simulation and performance evaluation of mobile-to-mobile (M2M) communication systems, it is desirable to develop accurate M2M channel simulation models for more realistic scenarios of non-isotropic scattering. In this paper, by using a 'double-ring' concept to describe M2M non-isotropic scattering environments, we propose new(More)

Observations provide evidence that the licensed spectrum is by far not fully used neither in time nor in space. Cognitive radio, which can sense its environment and location and then alter its frequency, modulation and other parameters so as to dynamically reuse the available spectrum, could break the current spectrum availability bottleneck.

The paper discusses the architecture of MIMO channel sounders. The semi-sequential design is contrasted with the sequential and the parallel architectures. Measurements with an eight parallel receiver semi-sequential sounder performed in both indoor and outdoor environments at 2 GHz using different antenna arrays will be presented. The parallel receiver(More)
