Abstract (en)
[origin: WO2012176108A1] A method is described for identifying transmitters (5-8) belonging to a single frequency network which transmit respective digital terrestrial radio-television signals, wherein each transmitter (5-8) transmits its own identifier coded in the service carriers of a plurality of N symbols (S40-S47) of a frame of the digital terrestrial radio-television signal, said method comprising the steps of: a) resolving, in the frequency domain and with respect to H, a linear system Y = X · H, wherein the indexes i and j vary between 1 and N, and wherein: - Y is a vector of N elements, wherein one element Yi of the vector Y represents a digital terrestrial radio-television signal acquired through a receiver (13) and relating to the i-th symbol of the plurality of N symbols of the frame; - X is a matrix having NxN size, wherein one element Xji of the matrix X represents a signal contribution that the receiver (13) would receive if the j-th transmitter were the only one to transmit on an ideal transmission channel the digital terrestrial radio-television signal relating to the i-th symbol; - H is a vector of N elements, wherein the element H, of the vector H represents the channel frequency response relating to the i-th transmitter; b) identifying each transmitter (5-8) through the respective identifier and the respective channel frequency response module.
