| Abstract | ||
| In this paper, a 16-QAM transmitter for software defined radio is designed and simulated using MATLAB-Simulink environments. The reconfigurable and reliable in the transmitter permit to do multiple functions of modulation schemes and pulse shaping in the same time. A software defined radio (SDR) technology could implement all transmitter requirements with less resources and power consumption. However, the transmitter part of SDR transceiver is investigated deeply for 70 MHz. The analysis of constellation and eye diagrams of multiple QAM schemes has been studied, examined and compared to achieve multiple system requirements. The experimental and simulation results shows an important development and the SDR transmitter style guide for current and future wireless and mobile systems. This development could support the 3G and accelerate the transformation to 4G. | ||
