1 Introduction
munications infrastructure that has e so much a part of daily life is expanding at
an exponential rate. Figure 1 illustrates the diverse range munication technologies used
virtually on a daily basis: wireless cellular (high and low mobility users), satellite, and microwave
links. To meet consumer, business and life-style demands infrastructure suppliers must build
sophisticated systems that no longer simply support telephony services, but provide voice, high
bit-rate data, video, image and multimedia capability. These systems must also interact with
sophisticated systems like the . Human nature dictates that there will be a range of
communication standards that evolve. There will also be a range of user terminals that need to be
connected to this munications tapestry, including cell phones, video phones, satellite
phones, PDAs, puters and other puting devices. To flourish and
eed in this dynamic environment equipment suppliers must build highly flexible systems that
operate across multiple wireless and work standards. They must be able to rapidly
adopt new business models as they evolve, and they must be able to incorporate new signal
processing techniques that allow work capacity, increased coverage, increased
quality of service, or bination of the above. The answer to the diverse range of
requirements is the software defined radio.
Software defined radios (SDR) are highly configurable hardware platforms that provide the
technology for realizing the rapidly expanding third (and future) generation digital wireless
communication infrastructure. Many sophisticated signal processing tasks are performed in a
SDR, including pression algorithms, p
