Theoretical analysis of the spread spectrum PSM system using E-sequences and a preamble
説明
A spread spectrum pulse spacing modulation (SS-PSM) system using E-sequences and a preamble is considered. The preamble signal is used for block synchronization. The following performances are evaluated by theoretical analysis: (1) the data transmission rate; (2) the block error rate when the receiver detects the preamble correctly; (3) the synchronization performances (the probability of detection and the probability of false alarm); (4) the block error rate considering the synchronization performances; and (5) the efficiency. Consequently, the data transmission rate of the SS-PSM system is much higher than that of the conventional spread-spectrum pulse position modulation (SS-PPM) system. The block error rate considering the synchronization performance can reach the lower bound by making use of the preamble. The efficiency of the SS-PSM system is 2 times greater than that of the conventional SS-PPM system.
