Mohamed Shalaby, Doaa Helmy, Mona Shokair . Improvement of Interfered Cooperative Radio Systems by Applying Alamouti 2×1 Codes. International Journal of Computer Applications. 184, 50 ( Mar 2023), 6-10. DOI=10.5120/ijca2023922616
The under-water communication is mainly based on acoustic signals. In fact, this type of communication has a little interference. As this communication category may be used in nodes communication in a wireless sensor network WSN, the electromagnetic interference EMI is so vital that it should be studied. The EMI, in general, can lower a radio system performance. There should be a gain that can compensate the existing loss due to the interference. In this manuscript, a cooperative communication system that is operating in acoustic wave bands is assumed to be prone to interference. The system is mathematically modeled and simulated. There are two types of interference as well as noise. The loss in the system performance can be compensated by applying Alamouti 2×1 codes that can provide a high gain in signal to noise ratio SNR values. The simulation results show that the application of Alamouti 2×1 codes can compensate the degradation in performance due to the existing interference. In addition, their application results in a coding gain in SNR values as well as spectrum efficiency.
