Transmitter location estimation for radio environment map construction using software defined radio

This work focuses on the practical implementation of transmitter location estimation algorithms using software defined radio devices for the purpose of Radio Environment Map (REM) construction, which is used to determine primary user location and available channels for Cognitive Radio. To this end, a testbed is also set up and technical and physical details of this testbed are explained. The location of an immobile transmitter is estimated using the collected signal strength data from multiple receivers by applying one known technique: LocatIon Estimation based (LIvE) REM Construction Method, and one proposed technique: exhaustive search on the discrete map. The results of these estimations are explained and compared.
