Identification of Co-Channel Transmitters in a DVB-T Network

We consider identification of co-channel interferers in a DVB-T network. Identification is achieved by the demodulation and decoding of the Transmission Parameter Signaling (TPS) data stream. We propose three combining methods exploiting either the presence of pilot tones within the DVB-T signal or the knowledge of a channel estimate. Simulation results show that in the case of strong co-channel interference, the proposed methods outperform a reference method that is Maximum Ratio Combining (MRC). Some laboratory tests and field trials validate these methods in a realistic metrology context.
