-These systems [SDR] are usually described by modifiers such as, embedded, real-time, distributed, object-oriented, portable, heterogeneous, multithreaded, high-performance, dynamic, resource-constrained, safety-critical, secure, networked, component based, and fault-tolerant.
-Together, the growing number of wireless standards and the quest for seamless connectivity are creating a need for functional flexibility in future radios.

Articles

-Techno Concepts in Van Nuys, California developed a patented sigma delta architecture that can take an input form 1GHz to 6GHz and convert it directly to a digital baseband.
TechnoConcepts of Boston, reconfigurable Wi-fi
Modeling languages like the waveform description language WDL are aiming to provide an ideal high-level representation, avoiding limitations by the combination of aspects from different existing languages.
...the observed relation between signal processing code size and control code size, which is actually 2000 lines versus 8000 lines demands for a code generation solution...large parts of the code are very regular and with every change in the partitioning or scheduling, the implementation has to be changed substantially. On the other hand signal processing implementations are highly individual and can hardly be automated by some tool process.
