Performance Analysis of DS-CDMA Signal through MZ Modulator in optical SCM Signal Transmission
광 SCM 전송방식에서 MZ 변조기를 통과한 DS-CDMA 신호의 성능분석
Abstract
In this paper, it is analyzed the statistical characteristics on the transmission performance of the optical SCM transmission in the CDMA RF signal relay system. Using Mach-Zehnder modulator, optical signal is regenerated into CDMA RF signal. Transfer function model of mach-Zehnder modulator is approximated to the third power of the input signal using Taylor series. BER results are analyzed under the multiple access interference and multi-path fading environment.
