We investigate the use of multi-antennas at both ends of a point-to-point communication system over the additive Gaussian channel. We consider a system with t transmit antennas and r receive antennas in which the received vector v∈Cτ depends on the transmi ...
We develop an efficient adaptive receiver for joint equalization and interference cancellation for multi-user space-time block-coded transmissions. The receiver exploits the code structure and allows multiple user transmission over frequency-selective fadi ...
To realize dependable and profitable information and communication systems, computing resources (CPU, memory, network bandwidth) should be taken into account to a much wider extent than they are today. E-commerce infrastructure, such as application servers ...
Many communication systems are {\em bandwidth-expanding}: the transmitted signal occupies a bandwidth larger than the {\em symbol rate}. The sampling theorems of Kotelnikov, Shannon, Nyquist et al. shows that in order to represent a bandlimited signal, it ...
The goal of this thesis is to develop and design new feature representations that can improve the automatic speech recognition (ASR) performance in clean as well noisy conditions. One of the main shortcomings of the fixed scale (typically 20-30 ms long ana ...
Group communication provides communication primitives with various semantics and their use greatly simplifies the development of highly available services. However, despite tremendous advances in research and numerous prototypes, group communication stays ...
Algorithm choices and corresponding VLSI architectures for spatial multiplexing receivers in multiple-input multiple-output (MIMO) communication systems are described in this paper. Implementations of linear and successive interference cancellation receive ...

We develop an efficient adaptive receiver for joint equalization and interference cancellation for multi-user space-time block-coded transmissions. The receiver exploits the rich code structure and allows multiple user transmissions over frequency-selectiv ...
Maximum likelihood detection is an essential part of high-performance multiple-input-multiple-output (MIMO) communication systems. While it is attractive due to its superior performance (in terms of BER) its complexity using a straightforward exhaustive se ...

The mean-squared-error criterion is widely used in the literature. However, there are applications where the squared-error is not the primary parameter affecting the performance of a system. In many communication systems, for instance, the information bits ...
