Patent ID: 8838055

Claim:
A mixer system, comprising: mixer circuitry receiving an input of a Radio Frequency (RF) input signal and providing an output of a signal of the RF input sampled at a sub-sampling rate; baseband parametric control circuitry receiving the signal and measuring at least one parametric value of the signal and determining a mode of operation; and sampling period control circuitry receiving the at least one parametric value and the mode of operation and adjusting the sub-sampling rate based thereon, wherein the sampling ratio is adjusted to minimize power drain while ensuring performance of the at least one parametric value is satisfying a predetermined level; wherein the at least one parametric value comprises one of carrier-to-noise ratio (CNR), bit error rate (BER), and signal-to-noise ratio (SNR), and wherein the sampling period control circuitry is configured to determine a greatest amount of sub-sampling based for the sub-sampling rate based on the at least one parametric value.
