(1) Design a specific code division pilot-assisted channel estimation method for DS-CDMA systems. Implement both Equal Gain Combining (EGC) and Maximum Ratio Combining (MRC) techniques at the receiver. Perform Simulink simulations to measure BPSK bit error rate performance. Plot the relationship curves between bit SNR vs. channel estimation mean square error and bit SNR vs. BER. Explain the distinct physical implications of both combining schemes when BER reaches 0.01, including implementation considerations for pilot signal generation, correlation-based channel estimation, and combining weight calculations.

Implementation of RAKE reception for CDMA systems with performance comparison of Maximum Ratio Combining (MRC), Equal Gain Combining (EGC), and Selection Combining (SC) algorithms. The simulation uses 3 multipath components with half-chip delay between paths and 16-bit Walsh code spreading for source input.
