CET DIGITAL SAL PROCESSING
INTRODUCTIONSDR is a radio wherein the radio’s physical layer behaviour is primarily defined in software.
It is a radio wherein the operating parameters of frequency range, modulation type or maximum output power can be altered by making changes to software.

• SDR is one of the most important topics in the area of mobile and personal communications.
• SDR promises mobile communication technology a major increase in flexibility, capability and durability.
• As communication standards are moving forward more complex algorithms and management schemes are being introduced and they consume much more power than the older versions.

FEATURES
•RICA uses eclipse C IDE as the development tool, hence provides the programmers to map applications.
• ARM controller is also programmed in C.
• Accelerates development speed and reduces cost.
• Both RICA core and ARM core are 32 bit architectures.

SYSTEM ASSESMENT OFDM physical layer has been mapped into this
proposed system.
The system works in full duplex mode.
Data frames are fed into the individual RICA processors following a frame segmentation method.

CONCLUSION
Higher transmitter and receiver throughput with lower frequency is achieved.
Heterogeneous architecture targeting mobile SDR has been proposed.
The hardware platform is composed of an ARM controller and several Reconfigurable Instruction Cells based array processors.
