Methods and arrangements to decode communications
Embodiments may comprise logic such as hardware and/or code to reduce power consumption by, e.g., a device such as a station or relay by implementing prediction logic to decode and determine whether a communication affects the operation of the device. Some embodiments may comprise logic to receive at least a portion of a header of a frame from a physical layer and begin to decode the portion of the header of the frame without first checking the correctness of the value in the frame check sequence field.

Method for generating consistent cryptographic key based on wireless channel features
The present invention discloses a method for generating a consistent cryptographic key based on wireless channel features. First of all, channel estimated values ĥa, ĥb and channel estimate mean square error mse are obtained through channel estimate, and then quantized channel eigenvectors {tilde over (h)}a and {tilde over (h)}b are obtained through quantization coding; next, inconsistency between {tilde over (h)}b and {tilde over (h)}a is equivalent to obtaining {tilde over (h)}b at end b through virtual channel noise adding the channel eigenvector {tilde over (h)}a sent by end a, and signal-to-noise ratio snr Γ of the virtual channel is determined; a proper coding mode enc is determined according to the virtual channel snr Γ; both communication parties perform corresponding coding and decoding according to enc and thereby obtain an estimated value {circumflex over ({tilde over (h)}a of {tilde over (h)}a; finally, a cryptographic key generating function is applied to {tilde over (h)}a and {circumflex over ({tilde over (h)}a, whereby a cryptographic key kc is obtained.
