—A distance and speed estimation algorithm for OFDM based radar is analysed statistically. The maximum likelihood estimator is derived and compared to previous results. A connection to spectral analysis is drawn, simplifying the analysis of the estimator in question. Finally, a method to evaluate the performance of the algorithm is presented and conclusions(More)
Next generation sequencing (NGS) technologies have revolutionized cancer research allowing the comprehensive study of cancer using high throughput deep sequencing methodologies. These methods detect genomic alterations, nucleotide substitutions, insertions, deletions and copy number alterations. SOLiD (Sequencing by Oligonucleotide Ligation and Detection,(More)
—The design process of a joint radar and communication system employing OFDM is analyzed. In particular, the question on how to choose OFDM modulation parameters such as carrier distance, guard interval length, frame length or pilot design is studied. Such systems use the same OFDM frames to transmit data and image the surroundings, so both radar and(More)
— Cognitive Radios observe the spectral environment through spectrum estimation. In particular, reconfigurable Software Defined Radio architectures generate large amounts of sample data, which can be computationally expensive to analyse. Compression by time-shifted random preintegration prior to spectrum estimation reduces the amount of data to be(More)
There is tremendous potential for genome sequencing to improve clinical diagnosis and care once it becomes routinely accessible, but this will require formalizing research methods into clinical best practices in the areas of sequence data generation, analysis, interpretation and reporting. The CLARITY Challenge was designed to spur convergence in methods(More)
—In this paper, we present a measurement testbed for OFDM radar which uses USRPs as a front-end. The resulting system, using two USRPs and a laptop, requires little power and can thus be easily installed in vehicles to perform measurements for car-to-car or car-to-infrastructure applications. As an example, we show how signals parametrized according to the(More)
—We present a software radio-based testbed for live testing of OFDM radar algorithms. Unlike previous testing setups, the hardware used (Universal Software Radio Peripherals) was low-cost and low-power, thus making the measurement setup both flexible and easy to use. The hardware can be easily battery powered. Both stationary and mobile measurements in(More)
—A software architecture to rapidly develop and test radio networks in real and physical environments is proposed. Radio network terminals are developed in software and run on generic hardware to maximize reconfigurability. Due to the software nature of the radio terminals, radio networks can be simulated in a virtual environment, where physical channels(More)
—We analyse mobile propagation channels which occur in the context of car-to-car communications in the 24 GHz ISM band. From the information gathered, we design robust frame designs for combined radar and communication systems using high-bandwidth OFDM signals. Two solutions are proposed: the combination of a spread spectrum technique and a standard(More)
—The objective of this work is to emulate the behavior of the Universal Software Radio Peripheral as an example of an RF front-end hardware for software radios. The model includes digital and analog signal processing. The emulator is implemented in GNU Radio and is intended to be used as part of a wireless network simulator.
