| Résumé : |
Evaluating the performance of multiple access protocols (MAC) through the lens of Bit Error Rate (BER) is crucial for optimizing communication systems. BER measures the probability of errors occurring during data transmission. By analyzing BER under various MAC protocols, engineers can identify how these protocols handle collisions and channel access. This information is vital for choosing the most suitable protocol for a specific application. Protocols that are capable of reducing collisions will have a lower BER, which will lead to a more reliable data transmission. This evaluation process helps ensure efficient use of the shared channel and high-quality data delivery The objective of this thesis is to evaluate the performance of multi-carrier systems, particularly focusing on systems based on the MC-CDMA (Multi-Carrier Code Division Multiple Access) technique. This technique combines OFDM (Orthogonal Frequency Division Multiplexing) and CDMA (Code Division Multiple Access), leveraging the advantages of both systems, making it highly suitable for the requirements of 4G and 5G. We have attempted to use a new method to study and optimize the performance of the MC- CDMA system. We will apply genetic algorithms (GAs) for optimization. Then we have analyzing the importance of parameters using features selection methods . |
