    Abstract: An outdoor satellite receiving unit (ODU) receives several independent satellite signals, selects two signals with a switch matrix, downconverts the two signals to a bandstacked signal with a high and a low band signal, and outputs the bandstacked signal on the same cable to receiver units. Several satellite signals can be selected in groups of two or more and output to independent receiver units. Signal selecting is performed at the received radio frequency (RF) and bandstacking is performed with a single downconversion step to an intermediate frequency (IF). Channel stacking on the same cable of more than two channels from several satellites can be achieved by using frequency agile downconverters and bandpass filters prior to combining at the IF output. A slow transitioning switch minimizes signal disturbances when switching and maintains input impedance at a constant value.

    Abstract: A satellite interference canceling system cancels the interference between two or more signals received by a satellite receiver. The signals can be two signals experiencing cross polarization interference or signals that experience interference from other satellite signals. Gain and phase are applied to the received signals and then combined with the other signals to result in cancellation by subtraction. The gain and phase values needed to cancel the interference are derived from measurements of carrier-to-noise ratio (C/N) as an indication of the interference level. The C/N can be measured in the set-top box indoor unit. Coherency restoration is performed in receivers that downconvert the signals before performing interference cancellation.

    Abstract: A dynamically programmable RF receiver includes an adjustable bias voltage-controlled oscillator (ABVCO) that operates in both low-interference and high-interference modes. The ABVCO uses a drive current to generate an output signal whose frequency varies based on a control voltage. When a jammer detector detects an interference signal, a state machine adjusts the ABVCO from the low-interference mode to the high-interference mode. Reciprocal mixing between the interference signal and phase noise in the output signal is reduced in the high-interference mode by increasing the drive current to reduce the phase noise. The ABVCO switches to the high-interference mode when a bias control circuit sends a bias control signal to the ABVCO, causing the ABVCO to generate the output signal using a greater amount of drive current. A programmable register contains a control value that determines the magnitude of the bias control signal and ultimately the magnitude of the drive current.
