Link-Level Simulation of Decode-and-Forward Relay Systems

A link-level simulation was conducted to implement decode-and-forward relaying in this study. The simulation results primarily include Bit Error Rate (BER) and Block Error Rate (BLER) analyses. During the simulation process, various parameters were meticulously adjusted and optimized using iterative testing algorithms to ensure result accuracy. This involved implementing channel coding schemes (such as convolutional or LDPC codes), modulation techniques (like QPSK or 16-QAM), and relay processing functions including signal decoding, error checking, and re-encoding operations. Through these simulations, we conducted in-depth performance analysis and evaluation of decode-and-forward relaying, providing critical references for further research and applications. Additionally, enhancements were made to the simulation framework and algorithms by incorporating Monte Carlo methods and parallel computing techniques to improve simulation accuracy and reliability. Overall, this research provides valuable information and datasets for link-level performance studies of decode-and-forward relay systems, establishing a foundation for future related investigations through well-documented MATLAB/Python-based simulation code with configurable channel models and protocol parameters.
