A broadcast communication system includes a plurality of transmitter tower stations configured to exchange inter-tower communication (ITC) signals to support a wireless ITC network (ITCN). Each TTS includes a transmitter (Tx) antenna, at least one receiver (Rx) antenna, and an ITCN server configured to form outgoing ITC signals for transmitting with the Tx antenna and to process incoming ITC signals received with the at least one Rx antenna. Each of the TTSs is configured to multiplex outgoing ITC signals with broadcast services signals prior to the transmitting and to detect the incoming ITC signals in a wireless signal received with the at least one Rx antenna. Several ITCN-integrating broadcast systems operating in a same or different frequency band may be interconnected to support an integrated inter-tower wireless communication network.

Inter-tower wireless communication network for terrestrial broadcasting systems

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.
