Cognitive Radio Kit (CR Kit)

GENI CR Kit

Open Source Platform

Range of COTS baseband FPGA platforms Medium size (LX50) Large size (SX95)

Standard interfaces: 1000 BaseT, (SFP) USB (8x PCIExpress)

4 (2) configurable radio modules (phased or smart antenna capable):

SDR – 25 MHz, ISM WDR – 25 MHz, 0-7 GHz XDR – 500 MHz, 0-7 GHz

Application framework with support for both RTL and Matlab (Simulink)

WINLAB

WDR RF Front-end (Curr: WDR v2.02) One to four independent radio

modules on one (FPGA) processor. Each module allows two up to 40

MHz bands from 100 to 7500 MHz• 12 bit ADC sampling up to 80MSps

on both I and Q rails.• NF = 6dB, optional external LNA for

customized applications.• 70dB of RX gain control.• 14 bit DAC sampling upto 200MSps

on both I and Q rails.• +20dBm TX output power with fast

gain control.• 60 dB of TX gain control

Supports full duplex operation. 1 usec RF frequency switching time Switched antenna diversity for both

TX and RX channels Comprehensive reference clock

selection or generation with internal, external or digitally derived sample clocks.

Extensive built-in-test for monitoring system status and health (including loopback).

• 14 layer PCB with high-frequency 5.5 mil thick NELCO N4000-13 material• 6000 part footprints with more than 4800 parts

WINLAB

CR Kit Framework

Features

Fully functional FPGA development platform with pluggable user applications.

Two environments: MATLAB/Simulink or VHDL/Verilog/BlueSpec

Communication with host using GbE links

Streamlined FPGA building process e.g. “HW design made-easy” using MATLAB/Simulink and build scripts.

WINLAB

CR Kit User Applications

APP subsystem: Build App as separate

entity in MATLAB/Simulink, then integrate into Framework.

Integration of Tx and Rx subsystems

Well-defined IO interfaces between APP and Framework.

Either develop own Tx/Rx Apps, or select from libraries

WINLAB8

CRKit Future Plans

Conversion of waveform to more modular form (BlueSpec)

Validation of waveform control across wide-band front-end

Further development of basic communication blocks (GENI Radio Library)

Multi-FPGA support and design partitioning Wider GENI deployment

WINLAB

GENI The Global Environment for Network

Innovations (GENI) is a nation-wide infrastructure being designed, developed and deployed to support experimental research in network science and engineering.

Networks are broadly defined with multiple layers of abstraction, from physical substrates, through the architecture and protocols, to networks of people, organizations, and societies

• GENI Spiral 3Early experiments, meso-scale build, interoperable control frameworks, ongoing integration, system designs for security and instrumentation, definition of identity management plans.

• Envisioned ultimate goalExample: Planning Group’s desired GENI suite, probably trimmed some ways and expanded others. Incorporates large-scale distributed computing resources, high-speed backbone nodes, nationwide optical networks, wireless & sensor nets, etc.

GENI grows through a well-structured, adaptive processSpiral Development Process

Re-evaluate goals and technologies yearly by a systematic process, decide what to prototype and build next.
