Design and Implementation of DS-CDMA Modem Using BPSK
Objective
The objective is to simulate and implement DS-CDMA signal transfer using BPSK modulation, leveraging MATLAB for efficient data communication.
Abstract
This article describes the simulation and implementation of the Direct Sequence Code Division Multiple Access (DS-CDMA) data transfer of the signal for the modem architecture. For both data transmission and reception, we use a modulation technique called Binary Phase Shift Keying (BPSK). The direct sequence spread spectrum is exploited by CDMA. CDMA facilitates the flow of data between several users. The system's distinguishing characteristics are its quick data rate and low bit error probability. We used Direct Sequence Spread Spectrum (DSSS), which is similar to CDMA in that the modulated signal spectrums generated by the PN sequence are transmitted first, and then the FFT shows the FFT spread spectrum. MATLAB simulates different intermediate outputs using digital format to accomplish signal modulation and demodulation. In this work, signals are displayed.
Keywords – MATLAB, FFT, BPSK, DS-CDMA, DSSS.
