STTR Phase I: Phase-Modulated Antennas for Bandwidth-Efficiency and Cost Reduction

该小型企业技术转让（STTR）第一阶段研究项目旨在证明直接相位天线调制（DPAM）的可行性，DPAM是一种创新的无线通信信令技术，有望大大提高频谱效率和多用户干扰，同时降低硬件复杂性和组件成本。所提出的方法使用天线结构的特定新颖特性来执行调制和解调，从而绕过对发射器或接收器电子器件中的这些块的需要。通过结合传统的正交相移键控（QPSK）信令使用新颖的每符号正交比特，可以实现固定频谱分配的数据速率和服务质量的加倍。这种DPAM技术有望增强广泛使用的QPSK格式，将带宽效率提高50%，同时降低系统复杂性和成本。带宽的这种增加会对无线通信产生很大影响，因为无线电频谱（固定资源）正变得越来越拥塞。该技术可支持未来版本的802.x无线数据、个人通信和遥测服务，适用于消费者、政府、军事和公共安全应用。DPAM还提供关于多用户隔离的改进，并且还承诺改进的抗干扰性。

This Small Business Technology Transfer (STTR) Phase I research project aims to prove the feasibility of Direct Phase Antenna Modulation (DPAM), an innovative wireless communication signaling technology that promises to greatly enhance spectral efficiency and multi-user interference, while reducing hardware complexity and component cost. The proposed approach uses specific novel properties of an antenna structure to perform modulation and demodulation, bypassing the need for these blocks in transmitter or receiver electronics. A doubling of data rate for a fixed spectrum allocation and quality of service can be achieved through use of a novel orthogonal bit per symbol in conjunction with traditional Quadrature Phase Shift Keying (QPSK) signaling. This proposed DPAM technology promises to enhance the widely used QPSK format, improving bandwidth efficiency by 50% while reducing system complexity and costs. Such an increase in bandwidth can have a large impact on wireless communications as radio spectrum, a fixed resource, is becoming more and more congested. This technology can support future versions of 802.x wireless data, personal communications, and telemetry services for consumer, government, military, and public safety applications. The DPAM also provides improvements with respect to multi-user isolation and also promises improved resistance to jamming.
