Automatic decision threshold level control (ADTLC) in direct-sequence spread-spectrum systems based on matched filtering
Savo Glisic · IEEE Transactions on Communications · 1988
An automatic decision threshold level control (ADTLC) algorithm for direct-sequence spread-spectrum systems is described and analyzed. Two parameters of interest, probability of false alarm P/sub a/ and probability of correct signal detection P/sub d/, are controlled simultaneously. As an example, the implementation of the algorithm in several practical direct-sequence spread-spectrum receivers is discussed. A considerable advantage of this algorithm compared to the classical approach (constant false alarm probability control) to the problem is demonstrated.>
