Bachelor Thesis: Implementation of a Software-Defined Radio testbed for OFDM-MIMO communication systems.

Alireza Zaeemzadeh __ University of Tehran __ 2014

This module consists of blocks requirung for building a MIMO system in GNU-Radio. The system is tested on USRP1 devices. Thanks for your interest in my code. This github project contains many different mini-projects. The one that I actually tested on hardware and worked successfully is the MIMO OFDM with Alamouti coding (which was the main project and a part of my senior design for the B.S. degree). All the other designs are starting points of other projects in the lab that I used to work in. So, all the designs with MAC layer (such as “FinalDesign”) and designs with QPSK modulation (such as “qpsk_mimo_usrp”) are not complete works and probably do not work on hardware immediately (you have to work on them a little bit).

##Testbed Specifications:

• SDR Platform: USRP1
• Daughterboard: WBX
• Channel: TX/RX
• Antenna: VERT900
• Frequency: 1900 MHz

##Directories:

• lib : C++ codes for different blocks
• grc : *.xml files for blocks
• examples: you can find screenshots of my designs here
• apps: *.grc files for some applications and high level blocks
