    CET DIGITAL SAL PROCESSING
  • 3. INTRODUCTION
    • SDR 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.

  • 5. BLOCK DIAGRAM OF SDR RECEIVER CET DIGITAL SIGNAL PROCESSING
  • 6.
    • 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.

  • 7. RICA ARCHITECTURE OVERVIEW RICA core design high level flow CET DIGITAL SIGNAL PROCESSING
  • 8. 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 .

  • 9. Hardware architecture diagram SYSTEM ARCHITECTURE CET DIGITAL SIGNAL PROCESSING
  • 10. SYSTEM DESIGN ENVIRONMENT
    • The design flow consists of two main steps:
    • ARM development suit (ADS)
    • RICA Eclipse C IDE.

  • 11. 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.
    CET DIGITAL SIGNAL PROCESSING
  • 12. ADVANTAGES
    • Maintainability enhanced.
    • Flexibility, capability and durability.
    • High receiver and transmitter throughput.
    • Low power compared to other programmable applications.
    • Easy programming model from high level C.
    CET DIGITAL SIGNAL PROCESSING
  • 13. 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.
