COMBINATION OF MULTIPLE PRECODING TECHNIQUES FOR MULTICARRIER MODULATION SYSTEMS

摘要

Systems, methods, and instrumentalities are disclosed to utilize a combined precoding technique in a multicarrier modulation system to reduce out-of-band power leakage. A combined precoder may be used to precede a symbol stream using a matrix-based precoding component to generate a first precoded symbol stream. The combined precoder may then be used to apply a perturbation to the first precoded symbol stream to generate a second precoded symbol stream.
