摘要： Briefly, in accordance with one or more embodiments, a platform may comprise a receiver to receive a signal that includes an error in the received signal due to a noise signal generated in the platform, and a processor configured to calculate a noise vector from a source of the noise signal. The noise vector may be de-spread. The receiver may include digital signal processing configured to estimate an error vector based at least in part on the noise vector and to subtract the estimated error vector from the received signal to cancel the noise signal from the received signal. The noise cancelled from the received signal may include platform noise generated by a bus, a memory circuit, a clock, a power supply, a circuit ground or integrated circuit substrate, or input/output circuit of the platform.

摘要： A terminal includes control logic to control a phase-locked loop to output a spread-spectrum clocking signal. The control logic controls the generation of the spread-spectrum clocking signal by adjusting at least one parameter of the phase-locked loop. The parameter may be a charge pump setting or a loop-filter capacitance of the phase-locked loop, or their digital equivalents. Adjustment of the parameter reduces a predetermined portion of a communications spectrum. The predetermined portion may be located within a range of frequencies allocated to a specific channel, and reduction of the spectrum in this range may serve to reduce noise associated with clocking harmonics.

摘要： In some embodiments, SSC (e.g., discrete SSC) profiles with intentional and controlled gaps may be used to mitigate interference for platform radios. Targeted frequency gaps are placed in spectrum of spread clocks and clock-derived signals where they may otherwise result in problematic RFI to a platform radio.
