Alternating phase filter for increasing communication speeds, spectral efficiency and enabling other benefits

摘要

Common wave and sideband mitigation communication systems and methods are provided that can be used with both wireless and wired communication links. The systems and methods provided can enable faster data rates, greater immunity to noise, increased bandwidth/spectrum efficiency and/or other benefits. Applications include but are not limited to: cell phones, smartphones (e.g., iPhone, BlackBerry, etc.), wireless Internet, local area networks (e.g., WiFi type applications), wide area networks (e.g., WiMAX type applications), personal digital assistants, computers, Internet service providers and communications satellites.

主权项

1. A communications apparatus, comprising:
a switch circuit that alternates positions based on a switch control input to alternate the phase of a signal; and a signal output circuit that outputs the signal having the alternating phase in response to the switch circuit, the outputted signal resonates in a first set of circuits but causes destructive interference in a different set of circuits.
