5. In a three-path Rayleigh channel for Direct Sequence Spread Spectrum: (1) Design a specific code-division pilot-assisted channel estimation method for DS-CDMA with receivers employing Equal Gain Combining and Maximal Ratio Combining. Implement Simulink simulations to measure BPSK bit error rate performance, plot bit-to-noise ratio vs. channel estimation MSE curves, and plot bit SNR vs. BER curves. Explain the physical significance of the two combining schemes at BER=0.01. (2) Assuming frequency synchronization is achieved, design a specific single-dwell sliding correlation timing synchronization method for DS-CDMA. Implement Simulink simulation using custom S-Function code to analyze timing synchronization accuracy and plot bit SNR vs. acquisition probability curves. (3) Assuming timing synchronization is achieved, design a specific frequency synchronization method for DS-CDMA. Implement Simulink simulation using custom S-Function code to plot bit SNR vs. frequency synchronization error curves.
