Abstract
In this SBIR solicitation, the US Air Force is seeking angle modulation receiver techniques which are able to process multiple overlapping signals simultaneously and maintain the information content of each signal. As a solution to the multiple overlapping signal reception, MaXentric is proposing two approaches. Both approaches relies on the idea of enhancing the signal of interest and suppressing other signal. We name them as Signal Enhance Interference Suppress Demodulator (SEISD). The first approaches utilize cyclostationary properties of modulation signals. A frequency shift filtering filter is applied to received signal to enhance the signal of interest and suppress the interference. Conventional demodulation techniques are then performed to extract the signal. The second approach is based on the interference cancellation techniques. The signal is demodulated and subtract from the received signal either in serial or in parallel to reduce the interference to other signals. Both approaches can reuse conventional demodulation techniques. The goal of Phase I will be to determine the feasibility and improvement to link performance offered by each approach.
