Abstract
A method of determining an acquisition indicator bit AIat a receiver in a communication system which includes receiving multiplexed acquisition indicator bits y=B×AI+n, where B is the signature matrix known at both base station and the receiver, AI is all the acquisition indicator bits and n represents noise. Next, an estimated value of the acquisition indicator bit AÎ(s) as a function ofis calculated, where B(s,.) is the s-th row vector of the transposed matrix Bfor acquisition indicator bit AI. Finally, the acquisition indicator bit AIis set as follows:=−1, if()<=0, if()<=1, if()≧where R and U are decision thresholds.
