Performance analysis of the SS-CSC system using synchronizing spreading code

In this paper, the performance of the spread spectrum communication constrained spreading code (SS-CSC) system using synchronizing spreading code is discussed. In particular, the bit error rate (BER) and the initial acquisition time are evaluated by theoretical analysis. Moreover, the performance of this system is compared with that of bi-orthogonal system. Consequently, it is found that the average acquisition time increases and the BER decreases when increasing E/sub info//E/sub sync/. Moreover, the SS-CSC system with the canceller is superior about 5.5[dB] to the system without the canceller when the BER is 10/sup -6/ and E/sub info//E/sub sync/ is 0.5. The SS-CSC system using a synchronizing spreading code had better use the canceller in order to reduce E/sub info//E/sub sync/. The BER of the SS-CSC system using the synchronizing code is the same as that of the bi-orthogonal system.
