Motivation

Multiple-antenna (MIMO) wireless systems are already commonplace in current wireless standards, such as 802.11n or LTE. The major drawback of MIMO systems is the large form factor associated to multi-antenna arrays, limiting the practical use of MIMO systems to base stations. Distributed MIMO systems have been proposed as an alternative to conventional MIMO systems in future communication networks: instead of having a single transceiver with multiple antennas, we consider multiple transceivers, each having a single antenna. These different transceiver will cooperate to emulate a conventional MIMO system. The major difficulty lies in the stringent synchronization constraints that need to be achieved between the different nodes of the distributed MIMO array.

Example of a distributed transmit beamforming system

Objectives

The objective of this Master thesis is to design and implement distributed synchronization techniques on a software-defined radio testbed of three or four nodes, using USRP-X310 or USRP-N210 software-defined radios. The student will have to implement the VHDL code and software (C++/Python) to achieve distributed synchronization using state-of-the-art techniques. The considered use case is to perform conventional beamforming with a distributed array of nodes.
