| - | Bachelor semester project: 2008-2009 | + | ==== Wireless communication system using Software Defined Radio platforms ==== |
| \\ | \\ | ||
| + | **Background:**\\ | ||
| + | Software Defined Radio (SDR) is a new paradigm that allows to change any aspect | ||
| + | of a communication protocol, including the signaling method, by changing the | ||
| + | software. The only limitation is the bandwidth of RF (radio frequency) part.\\ | ||
| - | ==== Télécommande ==== | + | At LCM (Mobile Communications Laboratory), we are currently |
| - | === Introduction === | + | using the bladeRF SDR platform (http://www.nuand.com/) for various |
| + | projects and purposes, including for example the acquisition of a GPS | ||
| + | signal (which is used in the SDR class).\\ | ||
| - | Dans le modélisme (voiture, avion, hélicoptère, ...) on a généralement recours à | + | \\ |
| - | des télécommandes. | + | **Objectives:**\\ |
| + | The goal of this project is to implement an over-the-air communication | ||
| + | system using two bladeRF modules, one at each end of the wireless link. | ||
| + | Some of the basic blocks are already implemented in Matlab (data source, | ||
| + | modulator, pulse shaper, matched filter, demodulator, error correction mechanism).\\ | ||
| + | In order to have a fully operational | ||
| + | wireless link, there are several modules that are still missing. The purpose of this project | ||
| + | is to implement them. First, one needs to | ||
| + | perform the clock synchronization between the transmitter and the receiver. | ||
| + | Next, one has to synchronize the received data and detect the start/end | ||
| + | of the transmitted blocks/frames. Finally, one has to estimate the | ||
| + | channel parameters, using some training data. Once these blocks are implemented, | ||
| + | a fully operational transmission chain should be demonstrated.\\ | ||
| - | Une télécommande fonctionne avec des pulses modulées en largeur (PWM) et le tout | + | \\ |
| - | modulé en FM. | + | **Prerequisites:** |
| + | Matlab, COM-302 Principles of digital communications (or equivalent).\\ | ||
| + | (COM-511 Software-defined radio: A hands-on course is a plus. This can be taken in parallel.)\\ | ||
| - | L'idée du projet est d'utiliser le « Softvare defined radio testbed » comme une télécommande. | + | \\ |
| + | **Laboratory:** LCM, IC faculty\\ | ||
| - | La partie réception est déjà implémentée mais il reste à faire la partie | + | \\ |
| - | d'émission. | + | **Project available for:** Master in Communication Systems / Computer Science \\ |
| - | === Mission === | + | \\ |
| + | **Number of students:** 1\\ | ||
| - | Implémenter sur la Software Radio la chaîne d'émission pour la télécommande. | + | \\ |
