How to Realise a Superior Modem

In this chapter, we have provided a brief review of the implementation challenges in designing cost-efficient BFWA transceivers. The overall architecture was our first point of attention. The top-level architectural choices are normally taken at a very early stage in the design process, and may have a tremendous impact on the quality of the final result. Flexible interfaces between hardware and software and between digital and analog processing were pointed out as crucial features.
