What is a Software Radio?

A software radio is a wireless communications device in which all of the signal processing is done by software. New capabilities can be introduced like a software radio is able to inter operate with different wireless protocols, incorporate new services, and upgrade to new standards, just by downloading a new software.

Is there any standard for developing SDR?

The Software Communications Architecture (SCA) specification sponsored by the Joint Tactical Radio System (JTRS) program

What are software and hardware requirements for developing SDR?

Radio communications engineers are faced with numerous challenges as radio technology moves towards Software-Defined Radio (SDR) from hardwired radios. The Joint Tactical Radio System (JTRS) program mandates the use of the Software Communication Architecture (SCA) for SDR systems. The SCA provides a common framework; but, communication engineers must work with software concepts such as Object Oriented Programming (OOP), Portable Operating System Interface (POSIX), and middleware using Common Object Request Broker Architecture (CORBA).

How to achieve SCA compliance?

The easiest way for SDR manufacturers to meet SCA compliance is to use an RTOS, ORB and Core Framework that have passed SCA compliance many times. There are a variety of real-time operating systems that have been used by SDR builders that have passed SCA compliance. Then use SCA compliant ORB.

Why only ORBexpress?

ORBexpress is the only ORB that has ever been officially tested for SCA compliance (and it passed every time for every radio manufacturer).

Is it mandatory to use CORBA for DSP and FPGA?

No. But do read the article by industry leader vendor for CORBA Why Multiprocessor DSP Systems Need CORBA to get the complete picture for ORB's role in SDR development.

Who are the resellers of ORBexpress in India?

InvariantLogic is the only vendor permitted to sell ORBexpress in India.
