Abstract:

In this talk, challenges incooperative multiple-input multiple-output
wireless channel modelling willfirst be reviewed. Then,a novel unified
channel model framework is proposed for cooperative MIMO wireless
channels. The proposed model framework is generic and adaptable to
multiple cooperative MIMO scenarios by simply adjusting key model
parameters. Based on the proposed model framework and using a typical
cooperative MIMO communication environment as an example, we derive a
novel geometry-based stochastic model applicable to multiple wireless
propagation scenarios. The proposed GBSM is the first cooperative MIMO
channel model that has the ability to investigate the impact of the
local scattering density on channel characteristics. From the derived
GBSM, the corresponding multi-link spatial correlation functions are
derived and numerically analyzed in detail.The talk will end with
discussing future challenges in MIMO channel models.
