Performance Analysis of Synchronization of the FH Spread Spectrum Systems

周波數跳躍擴散스펙트럼通信시스팀의 同期에 대한 考察과 初期同期過程에서의 同期與否를 판별하는 比較器의 臨界値(threshold)와 檢出確率(detection probability), 誤謬警報確率(false alarm probability)과의 관계를 구하여 同期裝置의 性能分析을 하였다.

The performance analysis of serial search spread spectrum synchronization system is carried out. To evaluate the synchronization probabilities, two chi-square densities for signal plus noise and noise only are derived. Then Neyman-Pearson scheme is applied to determine the threshold of the synchronization system. The synchronization probability curves are shown as a function of threshold and signal to noise ratios.
