Signal/circuit/full-wave co-design of resilient ultra-wideband wireless systems for the Internet of Things

Integrated wireless units for the Internet of Things and the fifth-generation (5G) wireless communication system must provide stable high data rates at a reasonable cost. These new ultrawideband (UWB) devices will be integrated in low-cost objects and deployed in adverse conditions that cause drastic variations in the antenna’s radiation characteristics and RF frontend’s operating point. This project provides a fundamentally new formalism to counter these variations and to guarantee the required data rates in all potential operation conditions. In a first step, the effects of random environmental variations on the wireless system’s figures of merit are quantified using a stochastic framework. Next, an innovative adaptive UWB wireless communication architecture is developed based on a pervasive signal/circuit/antenna co-design and co-optimization formalism. This system topology is able to counter random operating conditions by reconfiguring the transmit (TX) and receive (RX) antennas based on local TX/RX antenna mismatch feedback and overall wireless channel feedback. Simultaneously, this information is exploited to condition the digital signals in real time. These measures will ensure optimal UWB communication under all possible conditions by ensuring that the operating points of the antennas, the frontends, and the modulation and coding are optimally tuned to the current channel state and the antenna deployment conditions.
