INTERFERENCE ALIGNMENT FOR CHANNEL-ADAPTIVE WAVEFORM MODULATION

摘要

Embodiments provide an apparatus and method for interference alignment for channel-adaptive waveform modulation. The method includes obtaining at least a part of a first matrix and a part of a second matrix for the impulse response function of a communication channel. The method further includes designing a set of one or more linearly independent waveforms based on at least the obtained parts of the first and second matrices such that a first subspace spanned by the linearly independent waveforms when multiplied by the obtained part of the first matrix at least partially overlaps a second subspace spanned by the linearly independent waveforms when multiplied by the obtained part of the second matrix.
