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.

System and method of removing discrete spurious signals in cable broadband and other RF environments

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 sampling method implements direct RF sampling of the down-stream DOCSIS and Euro-DOCSIS cable plant signals present at the customer premises equipment (CPE).

Direct RF sampling for cable applications and other broadband signals

A scheme to provide a spectral view of the signals present at the customer premises equipment by the network operator and includes a digital signal processor (DSP) or other signal processing apparatus integrated into a customer premises equipment (CPE) tuner in which the DSP or other signal processing apparatus is operational to perform a spectral analysis.
