  • Patent number: 10771208
    Abstract: A primary transmitter of a multicast communication system transmits in-band backhaul to a relay transmitter using an LDM signal that also carries services to end-users. The relay transmitter processes received wireless signal to extract the in-band backhaul and re-transmits services obtained from the in-band backhaul in same or different frequency channel. The in-band backhaul may be transmitted in a high-capacity layer of the LDM signal carrying or in a separate timeslot. Transmitter-specific signature signals may be used for loopback and forward channel estimation at the relay transmitter. The in-band backhaul may also carry service data for devices in a different network.

  • Patent number: 9479826
    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.
