  • Patent number: 8855022
    Abstract: A method and system for increasing throughput in a hierarchical wireless network is described. The hierarchical wireless network includes a plurality of nodes and each of the plurality of nodes has a primary path to the root node. First, one or more channels from a plurality of available channels are allocated to each disjoint sub-tree associated with the root node. Then, alternate one or more disjoint paths from at least one node in the plurality of nodes to the root node through alternate disjoint sub-trees associated with the root node are determined. Next, data from the at least one node is sent to the root node through a primary path and one or more alternate disjoint paths.

    Abstract: The present disclosure provides methods and systems for automatic gain control (AGC) in a multiple input multiple output (MIMO) system having two or more receiver chains, each receiver chain including a receiver and an AGC module. The AGC system accepts a signal at a compensation module associated with the receiver chain and calculates one or more gains using the AGC module associated with the receiver chain. Then, an estimation module computes a scaling factor for each receive chain from the gains and transmits the scaling factor to the compensation module of the respective receiver chain, which requantizes the signal based on the scaling factor.
