3G and 4G Communication System Interference Remediation Techniques

The objective of the proposed research project is to develop novel algorithms and signal processing techniques that will minimize Aegis-to-3G & 4G and 3G & 4G-to-Aegis interference. We will perform an investigation and research of new RF waveform characteristics that could enhance Aegis BMD coexistence with civilian 3G and 4G communication networks. Under this effort, we will design innovative RF techniques (i.e. modulation, timing and phasing) that can help increase AN/SPY-1 S-band radar compatibility with civilian 3G and 4G communication networks. These new RF waveforms will be largely compatible with the existing AN/SPY-1 S-band radar. The associated processing algorithms that will support the new RF waveforms will be developed, as well. The output of the Phase I will be a proof of concept design / study and identification of designs / models and test capabilities. A feasibility assessment for the proposed model, techniques, and methods proposed will be conducted. We will clearly validate the viability of the proposed solution during the Phase I effort resulting in a clear concept of operations document.
