Abstract

As communications technology continues its rapid transition from
analog to digital, more functions of contemporary radio systems are
implemented in software, leading toward the software radio. This article
provides a tutorial review of software radio architectures and
technology, highlighting benefits, pitfalls, and lessons learned. This
includes a closer look at the canonical functional partitioning of
channel coding into antenna, RF, IF, baseband, and bitstream segments. A
more detailed look at the estimation of demand for critical resources is
key. This leads to a discussion of affordable hardware configurations,
the mapping of functions to component hardware, and related software
tools. This article then concludes with a brief treatment of the
economics and likely future directions of software radio
technology
