Software implementation of wireless indoor communication system using coherent QAM

The paper presents a software implementation of the coherent quadrature amplitude modulation (CQAM) technique for wireless indoor communication. The proposed system can provide continuous data communication over changing environments. The software is developed according to block diagram execution. The block diagram oriented system provides an easy-to-use and modular structure while creating an environment for developing adaptive communication algorithms. The CQAM technique also increases the transmission data rate within a limited bandwidth according to the SNR value for indoor wireless communication. Test results reveal that software implementation of the CQAM technique for indoor wireless communication provides a flexible platform for high speed and complex computing.
