Cognovo demonstrates SDM Development Platform for Soft Modem Validation

Wed, 02/09/2011 - 8:04am
Cognovo announces the availability of its SDM Development Platform for integration, validation and interoperability testing of software defined modems created using the Cognovo software development kit. Cognovo's LTE soft modem will be on demonstration at Mobile World Congress in Barcelona by appointment.

Cognovo has partnered with 4M Wireless and Rohde & Schwarz to provide licensees and partners with an end-to-end integration and validation platform for Software Defined Modem development.

Once Layer 1 control and data (PHY) processing has been integrated and validated against reference tests vectors using the Cognovo Software Development Kit, developers can move immediately to protocol stack integration and conformance testing with the R&S CMW500 wideband radio communication tester from Rohde & Schwarz.

The Software Defined Modem from Cognovo can support many cellular and other wireless interfaces without the addition of specific ASIC hardware, being configured only by software. It is dimensioned to support all standards up to LTE.

Cognovo's LTE soft modem demonstration at this year's Mobile World Congress features the SDM Development Platform running an LTE downlink, integrated with the 4M Wireless LTE protocol stack and tested against the R&S CMW500. The combination of Cognovo's depth of real-time trace with the CMW500's breadth of test capability enables rapid and full IOT and conformance testing.

Cognovo's SDM-DP features a Modem Compute Engine (MCE) with external I/O for debug, trace and test peer connectivity. The MCE implementation is functionally equivalent and cycle accurate to the customers' own target silicon and enables both real time and non-real time operation to the R&S CMW500.

The 4M Wireless PS100 LTE stack was selected by Cognovo as it is the most widely used commercial LTE protocol stack available today that has been tested in the field with all major LTE infrastructure vendors. The ease of integration of the LTE stack with the Cognovo' Platform highlights the modularity and portability of the protocol stack software.
