One embodiment of the present invention includes a method for controlling a gain of a wideband signal. The method comprises adding a virtual channel to the wideband signal, the wideband signal comprising at least one channel. The method also comprises monitoring an output power associated with the wideband signal that includes the at least one channel and the virtual channel. The method further comprises setting a gain factor to achieve a predetermined output power of the wideband signal and amplifying the wideband signal based on the gain factor.

Automatic gain control for a wideband signal

A system and method of removing discrete spurious signals in cable broadband environments as well as in other RF environments employs either non-decision directed or decision directed techniques in order to remove the discrete spurious signals. The non-decision directed technique converts the signal of interest such that the spurious signal's frequency is approximately zero, filters out the converted spurious signal, and then reconverts the signal of interest back to its original location. The decision directed technique employs a decision mechanism such as a slicer to regenerate a spurious signal that is subtracted from the signal of interest containing the actual spurious signal such that the actual spurious signal is removed from the signal of interest.

A technique associated with transceiver systems solves transmitter impairments when the system has both receiver and transmitter operating with the same local oscillator frequency but with independent phase and gain impairments.

Method of fixing frequency complex up-conversion phase and gain impairments

A method is provided for equalization of nonlinear distortion in a distorted signal comprising the steps of: digitizing the distorted signal and passing the digitized distorted signal through an inverse non-linear transfer function to equalize the nonlinear distortion. Other systems and methods are disclosed.
