The rapid growth in cellular communications has proved that wireless
communication is viable for voice and data services. Traditional
wireless devices are designed to deliver a single communication service
using a particular standard. With the steady increase in new wireless
services and standard, single purpose devices, dedicated hardware
resources can no longer meet the user's needs. It is also expensive to
upgrade and maintain a wireless system each time a new standard comes
into existence. A feasible solution to make communication systems more
flexible and user friendly can be achieved through the Software Defined
Radio (SDR) concept. This book, therefore, provide design, simulation,
implementation and verification of a proposed SDR system including six
bandpass modems (modulation/demodulation) schemes with selectable
technique between them. These modems satisfy the WIMAX standard. These
modems are BPSK, QPSK, 8QAM, 16QAM, 32QAM and 64QAM.This book should be
useful for researchers and manufacturers that work on development of
wireless communication systems by using SDR emerging technology that has
the advantage of flexibility over conventional radio systems.
