  3. Abstract:
  4. MIMO (Mulitple Input Multiple Output) localization has attracted much attention recently. In such schemes, using multiple antennas at transmitter and receiver sides provides spatial diversity. On the other hand, Passive Coherent Location (PCL) by using the illuminators of opportunity (such as FM, GSM, DVB transmitters) has shown a number of advantages. In this paper, we explore the possibility of achieving diversity gain by using multiple non-cooperative transmitters. In earlier works on MIMO localization, cooperative transmitters were assumed, so that orthogonality between transmitted waveforms could be granted. However, such orthogonality condition is not assumed in the case of PCL schemes, for example in the case of DVB-T single frequency networks (SFNs)
