摘要： The present invention is a wireless communication system and method. In an exemplary embodiment, the system includes a plurality of transceiver nodes arranged in a network and configured to communicate between transceiver nodes using an Orthogonal Domain Multiple Access (ODMA) frame structure, each of the plurality of transceiver nodes having neighboring nodes. Each ODMA structure may include a plurality of bootstrap slots for each of the plurality of transceiver nodes. Further, a plurality of correlation sequences may be defined within each of the plurality of bootstrap slots in which each correlation sequence included within the plurality of correlation sequences is located in a separate antenna sector and sub-sector. Addition of the plurality of correlation sequences to each of the plurality of bootstrap slots allows for recursive directional determination of which antenna sector and sub-sector is to be used to communicate with one of the plurality of transceiver nodes.

摘要： A method of communicating in a mobile ad-hoc network is disclosed. It is determined whether a first directional transmission path between a transmitting node and a destination node is known to be free from obstruction. The transmitting node transmits a message to the destination node using the first directional transmission path. The message is retransmitted to the destination node using the first directional transmission path when a message receipt acknowledgement in an omnidirectional network transmission has not been received within a predetermined time. Additional transmissions via the first directional transmission path are blocked when the message receipt acknowledgement has not been received after more than a pre-set number of retransmissions. The message is transmitted to a proxy node using a second directional transmission path between the transmitting node and the proxy node, with instructions for the proxy node to directionally transmit the message to the destination node.

摘要： A method of determining transmission parameters for a wireless transceiver is disclosed. According to the method, a state table is loaded into a transceiver. The state table includes a plurality of states, each of which has a set of transmission parameters associated therewith. Based upon characteristics of the signals received from a signal source, the transceiver is assigned a first state. The received signals are received and processed using the set of transmission parameters associated with the first state. It is determined whether an observed behavior of the received signals exceeds a threshold associated with the first one of the plurality of states. The transceiver is assigned a second state when the behavior exceeds the threshold. The received signals are received and processed using the set of transmission parameters associated with the second state.
