Channel allocation was extensively studied in the framework of cellular networks. But the emergence of new system concepts, such as cognitive radio systems, has brought this topic into the focus of research again. In this paper, we study in detail the prob ...
In multiple-user communications, the bursty nature of the packet arrival times cannot be divorced from the analysis of the transmission process. However, in traditional information theory the random arrival times are smoothed out by appropriated source cod ...
This paper proposes multi-user precoding schemes for MIMO wireless networks. We design precoders that minimize the interference power caused by a user on all other users, as opposed to forcefully nulling the interference. The resulting scheme relaxes the t ...
In multiuser MIMO downlink communications, it is necessary to design precoding schemes that are able to suppress co-channel interference. This paper proposes designing precoders by maximizing the so-called signal-to-leakage-and-noise ratio (SLNR) for all u ...

Abstract—Rate and diversity impose a fundamental tradeoff in communications. This tradeoff was investigated for IntersymbolInterference (ISI) channels in [4]. A different point of view was explored in [1] where high-rate codes were designed so that they ha ...
The robustness of the delivery of digital compressed video streams has always been one of the main topic of the standardization bodies to assure the Quality of the Service (QoS). The MPEG standard which is nowadays the reference for digital television defi ...
We develop channel estimation techniques for multiple-input multiple-output (MIMO) channels that employ space-time block-coded (STBC) transmissions. We derive the MMSE channel estimator for multi-user Alamouti STBC transmissions over both flat fading and f ...
In this thesis we study coding strategies for single-user block-fading channels. The block-fading channel is a simplified model of slowly varying wireless communication channels with stringent delay constraints. This model is particularly important in prac ...
We develop adaptive channel estimation techniques for multiple-input multiple-output (MIMO) channels with space-time block-coded (STBC) communications. We describe a unified framework for adaptive channel estimation for multi-user Alamouti STBC transmissio ...
