How to Perform Very Wideband Digital Filtering in Modern Software Defined Radios

WithFred Harris, Elettra Venosa, Xiaofei Chen

This chapter describes a particular class of multirate filters and

the potential that they bring to communication systems and in

particular to modern wideband software radios. Multirate filters

have the capability of optimizing the sample rate while processing

signals and this characteristic provides many advantages to digital

systems. Cost and computational complexity reduction, improved

performance and reduced chip size, power and weight are just some

of them.
