Hentschel T. Sample Rate Conversion in Software Configurable Radios

Издательство Artech House, 2002, -281 pp.A whole book on sample rate conversion? When working in the field of software radio, I quickly became aware of a new problem in communications terminal design.
One main property of software radio terminals is the independence from existing standards defining an air interface. Thus, software radio terminals have the ability to process many various communications standards. These standards are generally based on different master clock rates and therefore employ different bit/chip rates. A solution to cope with the diversity of master clock rates in one terminal is to have a dedicated master clock for each standard of operation. This kind of solution is not only costly, it limits the applicability of a realized terminal to what is defined by the implemented clock rates. Hence, it is much more elegant to run the terminal on a fixed clock rate and perform digital sample rate conversion controlled by software.
But is sample rate conversion not a well-investigated field with lots of solutions? Indeed, there are many solutions. However, none of them serves the requirements of an application in communications terminals. Complexity and power consumption are the main issues in terminal design. On the other hand, often only one channel out of a wide-receive bandwidth needs to be processed. Hence, I sought solutions to perform sample rate conversion where certain errors are allowed. This led to an investigation of the topic of sample rate conversion from its beginning.Sample Rate Conversion in the Context of Software Radio
