| Popis: | The aim of this work is to perform an analytic comparison between adaptive modulation (AdM) and adaptive Forward Error Correction (AdFEC) in wireless network telecommunication systems. Through the Gilbert-Elliott model’s, the Packet Error Rate (PER) is calculated and both the throughput and the delay, for different modulations and error correction capacity, have been also investigated. For the throughput criterion adopted, the results show that the AdFEC performs better than AdM for higher values of Signal Noise-to-Ratio (SNR). However, when the SNR has low value the adaptive modulation performs better. For the delay criterion, the time to transmit a packet using AdM is lower than the time to transmit the same packet using AdFEC. |
