Abstract
Intelligent Automation, Inc. proposes Spectrum Efficient Communications and Advanced Networking Technology (SECANT), which integrates dynamic interference management (that adapts among interference avoidance, tolerance, cancellation, and interference alignment) and multiuser detection at the PHY layer. SECANT provides adaptive MAC design that supports PHY layer spectrum efficiency gains to improve system throughput on limited frequency resources and optimizes spectrum sensing and transmission times in a distributed network setting with possibly incomplete/inaccurate spectrum information. SECANT introduces a paradigm shift in wireless communication protocol design to achieve spectrum utilization beyond the legacy"single-link single-user"PHY-MAC operational range. We follow a cross-layer approach with seamless interactions between PHY and MAC layers to enable simultaneous transmissions and controlled interference resiliency in the system. This design provides wireless nodes with the unique capabilities of adaptively utilizing local information and optimally exploiting PHY layer resources to achieve spectrum efficiency significantly beyond the legacy design limits. Multi-layer design of SECANT is realistic in terms of cost-effectiveness and network performance, and allows practical SDR deployment for prototyping and testing under real radio hardware performance. We will study the performance of multi-layer SECANT design compared with SISO QPSK TDMA scheme via theoretical analysis, simulations, SDR implementation and wireless network emulation.
