SDR-3501 ISMRDP
International "Skinny" Military Communications (MILCOM)
Rapid-Prototyping and Deployment Platform

The SDR-3501 ISMRDP is a fully integrated, black-side software defined radio (SDR) platform providing a commercial off-the-shelf (COTS) "RF to Ethernet" radio platform for international military communications programs. The SDR-3501 ISMRDP integrates a high performance fast tuning transceiver with a Software Communications Architecture (SCA)-enabled signal processing platform that has been used for Joint Tactical Radio System (JTRS) waveform compliance testing.

This integrated solution was designed specifically to de-risk customers’ programs by providing the fastest route to developing SCA-enabled architectures and systems, waveform applications, and verification and validation platforms. The solution includes resource-efficient programmable digital down-converter (DDC) and digital up-converter (DUC) FPGA cores and a system-level software example demonstrating the overall data flow. Source code for the examples and DDC/DUC cores is provided. The SDR-3501 ISMRDP is at technology readiness level six for many fixed, airborne and maritime environments, making it suitable for field demonstrations and deployments.

RF Transceiver Subsystem

The RF transceiver subsystem consists of four basic elements from Digital Receiver Technology, Inc.: a DRT4011 tuner, a DRT4041 exciter, a DRT4051 highly stable oscillator, and a DRT4072 single board computer. A variety of packaging options are available including the DRT4001 Software Defined Radio Test System. This subsystem integrates the elements above into a single 20-slot 3U CompactPCI chassis. For more information on the DRT4001, please visit www.drti.com.

Signal Processing Platform

The SDR-3000 signal processing platform family was designed specifically for the requirements of software defined radio communications applications. It integrates heterogeneous processing elements (FPGAs, GPPs and DSPs (optional)) seamlessly using a high performance embedded fabric. The SDR-3501 ISMRDP uses Spectrum’s XMC-3321 analog I/O mezzanine module sitting upon one of the mezzanine sites of the PRO-3500 baseband processing engine to provide a single-slot modem solution. Due to its modularity and additional mezzanine site, the platform can also evolve with your future needs as Spectrum continues to expand its XMC-based I/O offering.

Software

In addition to the base software layers (Spectrum’s quicComm and SCA BSP) offered in the RF subsystem and the SDR-3501 platform, the SDR-3501 ISMRDP provides other valuable software and FPGA core functionality:

• The Harris dmTK, an SCA core framework and development toolset, fully integrated onto the SDR-3000 platform
• Optimized, programmable digital down converter (DDC) and digital up converter (DUC) FPGA cores interfacing to the IF
• Fully programmable FIR coefficients on up/down converters
• Capability to down convert multiple channels from same digital IF (optional)
• Highly resource-efficient cores due to serialized implementation
• Support for time sensitive and time slotted applications through:
• Time stamping of ADC input samples
• Time triggering of DAC output samples
• An RF control API to manage all functionality of the RF subsystem
• Wind River® VxWorks Real-Time Operating System and TAO CORBA
• A comprehensive data flow example from the RF input, through the entire signal processing chain, and back out the RF output

Source code for the RF control, hopping, DDC/DUC cores and time stamping is provided as part of the platform.
