LINEAR DISTORTION CANCELLER CIRCUIT |
摘要 |
The linear distortion canceller circuit (104, 104-1) obliterates the linear component of any amplitude and/or group delay distortion in a double-sideband, amplitude modulated carrier signal. Pursuant to the present invention, the carrier signal is split into first and second signals. The first signal is multiplied by a mixing signal at twice the carrier signal frequency and the mixed first signal is then added with the second signal. The disclosed apparatus and method can be used in a communications system utilizing QAM modulation. |
