Abstract: Waveforms for wireless communication are shaped asymmetrically according to a complex-valued weighted overlap/add (WOLA) filter. A wireless communication device generates a waveform corresponding to a carrier. The device determines whether neighboring carriers are being used for wireless communication. If one neighboring carrier is occupied and the other is unoccupied, the wireless communication device applies the asymmetrical filter to the waveform such that out-of-band signals which may interfere with the occupied carrier are suppressed to a greater extent than out-of-band signals potentially present in or around the unoccupied carrier. The wireless communication device then transmits the asymmetrically shaped waveform to maximize interference reduction and signal quality.
