An Implementation of Discrete Multi-Tone over Slowly Time-varying Multiple-Input/Multiple-Output Channels

Recent analysis of Multiple-Input Multiple-Output (MIMO) communication systems, for example those involving antenna arrays, has shown that channel capacity increases linearly with the number of antennas. This motivates the investigation of methods for data transmission over slowly time-varying MIMO channels. A low complexity method is introduced that e ectively diagonalizes the MIMO channel. Th...

The Multiple - Input Multiple - Output Systems in Slow and Fast Varying Radio Channels

Multiple-input multiple-output (MIMO) systems are well known as a technique which allows increasing the throughput of a radio link and overcoming the effects of multipath fading. However, the integration of MIMO systems into the standards of wireless networks is slow, as there are numerous problems still unsolved. This PhD thesis deals with MIMO systems in slow and fast varying radio channels. ...

On the capacity of multiple input multiple output broadcast channels

Abstract— We consider a multi-user multiple input multiple output (MIMO) Gaussian broadcast channel (BC), where the transmitter and receivers have multiple antennas. Since the MIMO broadcast channel is in general a non-degraded broadcast channel, its capacity region remains an unsolved problem. In this paper, we establish a duality between what is termed the “dirty paper” achievable region (the...
