Joint Optimal Power Control and Beamforming in Wireless Networks Using Antenna Arrays
(1997)
The interference reduction capability of antenna arrays and the power control algorithms have been considered separately as means to increase the capacity in wireless communication networks. The MVDR (Minimum Variance ...
Adaptive Blind Multi-Channel Equalization for Multiple Signals Separation
(1995)
This paper investigates adaptive blind equalization for multiple- input and multiple-output (MIMO) channels and its application to blind separation of multiple signals received by antenna arrays in communication systems. ...
Two-Dimensional Spatial Smoothing for Multipath Coherent Signal Identification and Separation
(1995)
The existing spatial smoothing (SS) technique, although it is effective in decorrelating coherent signals, is considered applicable only to uniformly spaced linear arrays which are very sensitive to the directions-of-arrival ...
Blind Adaptive Equalization of SIMO Channels Based on Second- Order Statistics
(1996)
This article investigates blind adaptive equalization for single- input/multiple-output (SIMO) channels. A second-order statistics based algorithm (SOSA) and a modified second-order statistics based algorithm (MSOSA) for ...
Algorithm-Based Low-Power Transform Coding Architectures- Part I: The multirate Approach
(1995)
In most low-power VLSI designs, the supply voltage is usually reduced to lower the total power consumption. However, the device speed will be degraded as the supply voltage goes down. In this paper, we propose new ...
VLSI Design of High-Speed Time-Recursive 2-D DCT/IDCT Processor for Video Applications
(1994)
In this paper we present a full-customer VLSI design of high- speed 2-D DCT/IDCT Processor based on the new class of time- recursive algorithms and architectures which has never been implemented to prove its performance. ...
Fast Blind Adaptive Algorithms for Equalization and Diversity Reception in Wireless Communications Using Antenna Arrays
(1996)
To combat the multipath and time-variant fading of wireless communication channels, antenna arrays are usually used to improve the quality and increase the capacity of communication service. This paper investigates the ...
Simultaneous Diversity Combining and Decoding for Fast Time- Varying Mobile Radio Channels
(1996)
In slowly time-varying mobile radio channels, adaptive diversity combining can reduce multipath fading of desired signal and suppress interfering signals. However, for fast time-varying fading channels, there exist no ...
A Fast Minimal-Symbol Subspace Approach to Blind Identification and Equalization
(1995)
A subspace-based blind channel identification algorithm using only the fact that the received signal can be oversampled is proposed. No direct use is made of the statistics of the input sequence or even of the fact that ...
Static and Dynamic Convergence Behavior of Adaptive Blind Equalizers
(1995)
This paper presents a theoretical analysis of the static and dynamic convergence behavior for a general class of adaptive blind equalizers. We first study the properties of prediction error functions of blind equalization ...
