摘要： Signals with unpredictable transmission properties enabling physically secure, unscheduled and interference-resistant machine-to-machine (M2M) communication are described. A physical dwell structure containing time slots and frequency channels is established, and a combination of unpredictable physical dwells, spread spectrum modulation with unpredictable spreading vectors, and unpredictable selection of intended receivers is described. These unpredictable transmission properties enable receivers to detect and extract transmissions intended for the receiver, and excise transmissions not intended for the receiver, even if they are received at much higher power levels than the intended transmissions. The system eliminates the ability for an adversary to predict and override M2M transmissions; allows reception of ad-hoc transmissions in dense environments without scheduling, carrier-sense multiple access with collision avoidance (CSMA/CA) protocols, or scheduling feedback paths; and allows macrodiverse reception of transmissions at networks of connected receivers, thereby providing additional efficiency and security improvements exploiting route diversity of the network.

摘要： A method and apparatus for generation of signals with unpredictable transmission properties allowing physically secure, unscheduled and interference-resistant communication over machine-to-machine (M2M) networks is claimed. A physical dwell structure comprising time slots and frequency channels is established, and a combination of unpredictable physical dwells, spread spectrum modulation formats employing unpredictable spreading vectors, and additional physical properties allowing unpredictable selection of intended receivers is described. These unpredictable transmission properties enable receivers employing blind detection and signal separation techniques to detect and extract transmissions intended for the receive, and excise transmissions not intended for the receiver, as part of the despreading procedure, and even if those transmissions are received at a much higher power level than the intended transmissions. The resultant system eliminates the ability for an adversary to predict and override M2M transmissions; allows reception of ad-hoc transmissions in dense environments without scheduling, CSMA/CA protocols, or feedback paths enabling scheduling, and allows macrodiverse reception of transmissions at networks of connected receivers, thereby providing additional efficiency and security improvements by exploiting the route diversity of the network.
