This letter presents a new probability expression for a multi-carrier (MC) DS/CDMA acquisition system with a reference matched filter (RMF). To evaluate the mean acquisition time (MAT) as a measure of the system performance, the probabilities of detection, miss, and false alarm are derived. From the results, it is shown that the MAT of the MC-CDMA hybrid system with RMF is comparable to the optimum mean acquisition time of the conventional MC-CDMA hybrid system, maintaining approximately the same degree of structuring complexity.
