Abstract:

An ideal Software Defined Radio is versatile and operates in multiple modes and bands. In order to achieve the desired versatility, the creation of a set of rules is necessary to standardize a radio system so that the radios could interoperate. One of the most accepted architectures as an accomplishment of this set of rules is SCA, wich uses CORBA as middleware. CORBA allows the use of several platforms in the functioning of a radio so that it operates with other radios using different platforms.This proposal uses GNU Radio,to process signals in a flexible way over a single processor, with the USRP board as front-end. Finally, the hypothesis of embedding the SDR system proposed in reconfigurable devices is raised, so that the portability of the system is allowed.
