Adaptive Modem for a Software Defined Radio System at Its Front End

Software Defined Radio (SDR) is the future Trend for mobile communication design. As, the hardware Merges into software gradually in communication system, SDR is supposed to facilitate high-speed multimedia Application for future mobile standards. SDR is flexible Reconfigurable and multi-standard system, which is Capable of providing efficient communication. An adaptive Modem forms an integral part of SDR system with robust and high data rate capability. The authors' project proposes the design and development of a module namely the Adaptive modem for the SDR system using LabVIEW as the tool. This project accomplishes performance analysis of Adaptive Modulation scheme in changing channel conditions. The various modulation schemes analyzed for adaptive modem are BPSK, 16 Quadrature Amplitude Modulation (QAM) and 64 QAM.
