Performance Comparison of FDMA and SC-FDMA Through Simulation

When analyzing the simulation performance of FDMA and SC-FDMA, a detailed comparison of their Peak-to-Average Power Ratio (PAPR) characteristics can be conducted. Implementation typically involves MATLAB scripts that generate orthogonal subcarriers using FFT algorithms for FDMA, while SC-FDMA incorporates an additional DFT-spreading stage before subcarrier mapping to reduce PAPR. Through further experimental studies and Monte Carlo simulations, researchers can investigate the performance of these techniques under various channel conditions, including multipath fading and frequency-selective environments. The simulation framework may include key functions for calculating complementary cumulative distribution function (CCDF) curves to quantitatively compare PAPR performance. Additional validation through extensive simulation data and experimental results can strengthen the conclusions, enabling more accurate assessment of both technologies' performance advantages and limitations for future communication systems. The code implementation typically involves parameter configuration for subcarrier allocation, modulation schemes (QPSK, 16QAM), and power amplification models to simulate real-world scenarios.
