Abstract:
A method for controlling power consumption in an electronic device, said device including a data receiver, a data transmitter, and means for performing a plurality of error detection and/or correction techniques at said receiver, said method comprising:receiving data having a given error detection and correction coding; determining an error rate corresponding to said data received in said receiving step, said error rate being determined by an initial one of said plurality of error detection and/or correction techniques; comparing said error rate to at least one error threshold value; and selecting, at said receiver, one of said plurality of error detection and/or correction techniques, based on an outcome of said comparing step, having a sufficiently complex and rigorous error detecting and/or correcting algorithm which, when applied to said data having said given error detection and correction coding, will ensure that said selected error detection and/or correction technique is one which consumes a lowest amount of power while maintaining a desired signal-to-noise ratio.
