  • Patent number: 6785513
    Abstract: A system and method for wireless broadband transmission in a scattering environment using a network of coherent repeaters. In one embodiment, the system comprises a number of groups of nodes. The nodes in a group are capable of broadcasting to each other and of beamforming to another group of nodes. A basestation broadcasts a number of signals at the same frequency and time. Each signal comprises a desired signal and multiple interference signals. The signals arrive at the nodes as co-channel interferers. The nodes are able to distinguish between the signals sent from each antenna of the basestation. Each of the nodes is further operable to transmit a repeated signal to a destination node such that the repeated signals collectively cancel out co-channel interference at the destination node. Therefore, the destination node receives a signal substantially free of co-channel interference.
