Correlator for a Basis-Space Architecture Ultra-Wideband Receiver
Ultra Wideband (UWB) signals have great potential for high data transmission and precise location. However, their wide bandwidth and low signal to noise levels make UWB receiver design via traditional methods difficult. New receiver architectures have been proposed that rely on the correlation of …

A non-coherent ultra-wideband receiver : algorithms and digital implementation
Ultra-wideband (UWB) communication is an emerging technique for wireless transmission in the 3.1-10.6 GHz unlicensed band with signal bandwidths of 500 MHz or greater. A non-coherent receiver based on energy collection reduces complexity, cost, and power consumption at the cost of channel spectral …

Design of a synchronization subsystem for an ultra wideband radio
Ultra Wideband (UWB) systems are receiving recently more attention due to its approval by FCC. The systems that have been already implemented are based in analog correlation. This thesis is part of an effort to implement a wholly digital Ultra Wideband receiver. Synchronization of a signal is a …

Spectrum monitor for cognitive radio
The concept of a cognitive radio assumes that the receiver is able to determine the activity level across a large range of spectrum in order to assign a channel for its use. Hence a key function is a spectrum monitor to detect the spectrum availability as a first step. This thesis explores the …

Radio Channel Measurements and Modeling for Smart Antenna Array Systems Using a Software Radio Receiver
… radio development. A four-channel, wideband, software-defined receiver was developed to serve as a test bed for wideband measurements and antenna array experiments. This receiver was used to perform vector channel measurements in terrestrial and air-to-ground environments using an …

New Concepts in Front End Design for Receivers with Large, Multiband Tuning Ranges
… presents new concepts in front end design for receivers with large, multiband tuning ranges. Such receivers are required to support large bandwidths (up to 10's of MHz) over very large tuning ranges (30:1 and beyond) with antennas that are usually narrowband, or which at best support multiple …
