Selecting High-Linearity Mixers for Wireless Base Stations

Today’s communication systems make strong demands on both receiver sensitivity and large-signal performance (dynamic range). When selecting components for a new design, therefore, it behooves the designer to focus on the performance of each one with regard to these requirements. In particular, this article deals with mixers and the basic parameters specified in their data sheets. The communicat...

High-speed High-resolution Data Converters for Base Stations: Technologies, Architectures and Circuit Design

This paper presents a possible evolution of base station architectures in the frame of the future global communication scenario. Moving from such a view the paper considers the technology trend and its influence on highspeed data converter design. Then, architectures of highspeed, high-resolution converters are resumed. Finally, design techniques and strategies for achieving the requirements of...

Integrating High Level and Low Level Planning

We present a possible method for integrating high level and low level planning. To do so, we introduce the global plan random trajectory η0 : [1, T ] → R, measured by goals Gi and governed by the distribution p(η0 | {Gi}i=1). This distribution is combined with the low level robot-crowd planner p(f, f, . . . , f | z1:t) (from [Trautman et al., 2013, Trautman and Krause, 2010]) in the distributio...
