Abstract

This chapter is about multirate signal processing and the potential that it brings to modern (software) radios. Optimizing the sample rate while processing signals provides many advantages to digital systems. Costs and computational complexity reduction, improved performance and reduced chip size are just some of them. Digital filters, up converters, and down converters are the basic elements for designing multirate architectures and their introduction ...
