Detailed Documentation
To achieve signal upconversion and downconversion, we conducted detailed simulation experiments and successfully verified the correctness of the process. In our implementation, we utilized advanced techniques including digital upconverters (DUC) and digital downconverters (DDC) with key functions such as interpolation/decimation filtering and complex mixing operations. The algorithm employed a multi-stage approach using FIR filters for efficient spectral shaping, with carrier frequency modulation/demodulation implemented through complex exponential multiplication. Through these experiments, which involved MATLAB simulations with proper sampling rate management and spectral analysis, we further deepened our understanding of signal frequency conversion. The verified implementation provides strong support and guidance for research and applications in related fields.
