Method and apparatus for frame control header decoding using cyclic shifting of bits

摘要

A method and apparatus for decoding a frame control header message in a wireless communication transmission are disclosed. The method comprises assuming at least some of the bits comprising the frame control header message are constant across multiple frames or are known a priori and generating metrics at least from the bits of the frame control header message that are assumed to be constant or are known a priori. The method further comprises decoding the metrics, for example, with a Viterbi decoder or using chase combining, to yield the decode frame control header message.
