Much of the initial excitement about MIMO systems
was due to pioneering work by Winters [132], Foschini [29], and Telatar [113] predicting remarkable
capacity growth for wireless systems with multiple antennas when the channel exhibits rich scatt

This paper presents the development of
software radio systems in a flexible and adaptive way. This
is achieved using a re-configurable communications stack
and the use of general-purpose processors.
Implementations and novel applications are pres
