BERT Products Now Support Low Density Parity Check (LDPC)

February 06, 2018
In addition to the diverse set of functions and features currently supported by GDP’s Model 650 Data Link Test Set (e.g. Noise, Jitter, Acquisition Time, Link Delay Measurement, and Convolutional Encoding), GDP’s BERT products now support the generation of Low Density Parity Check (LDPC) Forward Error Correction (FEC) codes outlined in the new Appendix R of the IRIG106 Telemetry Standard. Over and above the Appendix R codes, the BERT also supports the generation of the CCSDS Near Earth LDPC 7/8 Codes.
LDPC is a recently added function to telemetry links for new range applications due to its ability to significantly improve error performance. GDP’s telemetry receivers also support all of the LDPC codes on the downlink (Model 4426).
