Abstract
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 and to send the noise vector to the receiver, The receiver may include a digital signal processor 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.
