A sub-mW Tactical M-ary FSK Transceiver Communicating over 1km
Abstract
Dismounted Marines and low-cost UAVs currently communicate with each other and with mobilebasestations over distances of up to ~1km using radios that consume watts of power. This highpower dissipation is needed to ensure reliable communication using conventional physical layermodulation, coding schemes, and circuit design. Unfortunately, consuming watts of powernecessitates carrying of large batteries that hampers mobility and increases exertion levels ordecreases flight time for Marines and UAVs, respectively. In this program we aim to dramaticallydecrease the power required for reliable communication across ~1km by exploiting non-coherentorthogonal modulation schemes that, coupled with co-designed forward error correction codingschemes, enables a significant reduction in required SNR. Implemented with energy-efficient RFand digital baseband circuits, we aim for a total transceiver power below 1mW ~ a new benchmarkacross this distance. The essence of the research contribution is the cross-layer optimizationbetween PHY-layer design choices, coding complexity, and circuit power/performance trade-offs,all with a target towards reducing overall system-level power consumption. To ensure reliablecommunication with acceptable anti-jamming and low-probability of intercept properties, theproposed transceiver design will also incorporate frequency hopping strategies. Successfuldevelopment of the proposed cross-layer-optimized transceiver chipset will significantly reducethe power and weight burden of equipping Marines and low-cost UAVs with tactical radios.
