Abstract: A system has a first transmitter for transmitting a first wireless signal within a first frequency. A second transmitter is for transmitting a second wireless signal with overlapping frequency. The first transmitter and the second transmitter are disposed sufficiently proximate to another such that the wireless signals substantially interfere resulting in a combined wireless signal with negative SNR for each of the first wireless signal and the second wireless signal, the negative SNR being a result of at least the other of the first wireless signal and the second wireless signal. A receiver is located for receiving a received wireless signal comprising substantially interfering encoded data signals having negative SNR. The receiver is for selecting from the substantially interfering encoded data signals a signal of interest and for decoding said signal of interest relative to at least the other substantially interfering data signal within the received wireless signal.

Abstract: The invention relates to a transmitter identification system, which utilizes an identification signal embedded into a digital television signal, enabling the transmitter of origin to be identified at a receiving station. Ideally the identification signal is an orthogonal pseudo-random sequence time synchronized to the signal frame structure of the digital television signal. Particularly designed for single frequency networks, identification of the various transmitted signals enables the network to be tuned to eliminate or minimize multi-path effects at certain locations, which receive transmissions from various transmitters.

Abstract: The invention provides a method and device for iterative hybrid time-frequency domain block equalization of signals received via a communication channel subject to multipath interference. The equalization method includes frequency-domain equalization of blocks of received signals in a forward path, and time-domain inter-block echo correction and intra-block cyclic echo addition in the feedback path. The invention can be used for equalizing signals transmitted without cyclic prefix and subjected to multi-path interference with long delay spread.
