RAKE Receiver with 4-Path and 5-Path Multipath AWGN and Rayleigh Fading Channel

In a two-user RAKE receiver system, the implementation combines m-sequences and Gold sequences through 4-path and 5-path multipath AWGN with first-order Rayleigh fading channel to enhance receiver performance and channel reliability. The system employs multipath diversity combining where each RAKE finger is configured to capture and coherently combine different signal paths. Code implementation typically involves: 1) Generating orthogonal spreading codes using m-sequence and Gold sequence generators with specified polynomial configurations, 2) Implementing multipath channel models with AWGN and Rayleigh fading parameters, 3) Designing RAKE finger synchronization using correlation-based path detection algorithms, and 4) Applying maximal ratio combining (MRC) with channel estimation to weight and combine multipath components. Key functions include path delay estimation, channel coefficient calculation, and SNR optimization for improved bit error rate performance in fading environments.
