A frequency hopping sequential detection technique for in-net coarse acquisition

The authors present the results of a study assessing the impact that sequential detection has on the performance of the two-level frequency hopping coarse acquisition detector. The performance of the two-level detector is computed for the case where the active correlations use sequential detection and compared to the conventional case where fixed correlation times are used. The results show that sequential detection can significantly reduce the amount of hardware required to achieve a specified probability of detection in the presence of additive white Gaussian noise and partial band noise jamming under normal operating conditions. However, when the signal-to-interference level is low and/or the required detection probability is high, sequential detection requires more hardware than fixed direction.<>
