This project designs and demonstrates the feasibility of an innovative high performance low PAPR spectrally compliant communication waveform design for naval communication systems over multiple non-contiguous spectrum fragments via our unique polyphase non-contiguous carrier interferometry spreading spectrum technology. Novel spectrally coded (namely carrier interferometry code) waveforms are employed in non-contiguous OFDM technology to spread the information across available non-contiguous subcarriers. The spreading of the information over multiple subcarriers introduces frequency diversity and leads to higher BER performance in multi-path wireless channels. Furthermore, the information spreading equips the wireless network with anti-jamming capability. Additionally, the carefully chosen carrier interferometry code combines the benefits of single carrier transmission with multi-carrier transmission and provides much lower peak to average power ratio (PAPR) than that of current OFDM systems. Most importantly, by turning off the subcarriers which are not available due to spectrum availability or spectrum disturbance, and by adaptively reallocating the polyphase carrier interferometry spreading codes, the proposed wireless communication system provides the capability of operating over multiple non-contiguous spectrum fragments and maintaining the orthogonality among the spreading codes. As a direct result, our systems offer the best performance and throughput, as well as lowest PAPR, among all existing cognitive radio waveforms.
