Bilinear signal synthesis using polarization diversity.
Bilinear synthesis of nonstationary signals impinging on a multiantenna receiver has been recently introduced. The distinction in the spatial signatures of the sources provides a vehicle to reduce noise and source signal interactions in the time–frequency domain, and hence improves signal synthesis. In this letter, we utilize another form of diversity for enhanced source time–frequency signal representations. It is shown that cross-polarization antennas can be used to mitigate cross terms via simple polarization averaging.
