Patent ID: 7702036

Claim:
A method, comprising: encoding each bit sequence of a known bit sequence set with a code; receiving, at a controller, data in one or more time intervals, the data comprising part of a transmitted bit sequence indicating transmission parameters of a frame, wherein the transmitted bit sequence comprises a bit sequence of the known bit sequence set that is also encoded with the code and the frame comprises a plurality of time intervals; comparing, by the controller before all symbols of the bit sequence indicating the transmission parameters of the frame have been received and detected, the received encoded bits with corresponding bits of each known bit sequence of the known bit sequence set; selecting, by the controller based on the comparison, the bit sequence of the known bit sequence set which is determined to be closest to the received data; and determining, by the controller, the transmission parameters of the frame based on the selection; wherein the comparing comprises comparing based on calculation of a difference between the received encoded bits with the corresponding bits of each known encoded bit sequence of the known bit sequence set, wherein the calculation is based on the following equation: dist ⁢ ( i ) = 1 N TFCI ⁢ ∑ n = 1 N TFCI ⁢  TFCI cw , i ⁢ ( n ) - TFCI rx ⁢ ( n )  , where: dist(i) is the difference between the received encoded bits and the corresponding bits of an i th known encoded bit sequence of the known bit sequence set, N TFCI is the number of received encoded bits included in the comparison, TFCI cw,i (n) corresponds to an n th bit of the i th known encoded bit sequence of the known bit sequence set, and TFCI rx (n) corresponds to the n th bit of the received encoded bits of the encoded bit sequence indicating the transmission parameters of the frame.
