A successful approach for designing a compact reconfigurable antenna system using a single active and two parasitic reactance-loaded dipoles is proposed. The switched parasitic antenna (SPA) operates at 2.6 GHz using PIN diode technology. It is designed to ...
Cellular mobile networks are used by more than 4 billion users worldwide. One effective way to meet the increasing demand for data rates is to deploy femtocells, which are low-power base stations that connect to the mobile operator through the subscriber's ...
This paper describes the implementation of the hard computational kernels required for the baseband (BB) processing of a 2×2 multiple-input multiple-output (MIMO)-OFDM receiver on a design-framework for application specific processors. The employed low-com ...
A reconfigurable bandpass filter able to switch between WiFi and UMTS reception standards is presented. The topology allows achievement of two accurate centre frequencies, each associated with a precisely defined bandwidth, using six pin diodes. The design ...
We propose a new framework for MIMO decoding based on a recently developed technique for reliably conveying linear equations over wireless channels. Each transmit antenna sends an independent data stream using the same linear code. As a result, any integer ...

We present characterization of a two-pump parametric device for analog linear multicasting. Linearity of parametric multicasting is assessed from highly linearized input seed by two-tone intermodulation measurements. Experimental results confirm distortion ...
Under uncertain channel conditions, local and global power control factors for amplify-and-forward relay processing and source-destination beamforming are jointly and iteratively designed based on a minimum mean-square-error (MMSE) criterion. The influence ...
We study the impact of deployment of low cost, low power micro base stations along with macro base stations on energy consumption and capacity of downlink LTE. We add three important elements to the existing studies: a traffic layer analysis that take both ...
We revisit the topics of near-field adaptive beamforming and source localization following an alternative approach based on a spatio- temporal spectral representation of the acoustic wave field. With the proposed method, the wave field is expressed as a se ...

Email Print Request Permissions Save to Project Linear receivers are often used in multiple-antenna systems due to ease of implementation. However, traditional linear receivers such as the Decorrelator and the linear minimum-mean squared error (MMSE) recei ...
