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.

该小型企业技术转移（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，这是一种创新的无线通信信号技术，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。所提出的方法利用天线结构的特定新颖特性来执行调制和解调，绕过了发射器或接收器电子设备中对这些模块的需要。通过使用新颖的每符号正交比特并结合传统的正交相移键控 (QPSK) 信令，可以实现固定频谱分配和服务质量的数据速率加倍。所提出的 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。随着固定资源无线电频谱变得越来越拥挤，带宽的增加会对无线通信产生巨大影响。该技术可以支持面向消费者、政府、军事和公共安全应用的未来版本的 802.x 无线数据、个人通信和遥测服务。 DPAM 还提供了多用户隔离方面的改进，并承诺提高抗干扰能力。
