Nonbinary LDPC Decoder

A Forward Error Correction (FEC) subsystem is needed in almost all wireless communication systems.

Contact Provider Request Datasheet

Overview

A powerful Forward Error Correction (FEC) subsystem is needed in almost all wireless communication systems. Low-Density Parity-Check (LDPC) codes are a powerful family of FEC codes that allow for very low error-rates, approaching the Shannon capacity limit.

While binary LDPC codes have shown great performance, nonbinary LDPC codes have empirically shown even better performance, especially for small codeword lengths.

A configurable output synchronous FIFO is used to store the output for the next block.

Key features

  • Throughput matching the required specifications. 
  • Bit-error-rate and block-error-rate performance meet the required specifications. 
  • Compliant with BeiDou Navigation Satellite. 
  • Supports different code sizes 
  • Log domain implementation.

Benefits

Practical Considerations of LDPC Decoder Design in Communications Systems

This paper covers some practical aspects of designing the LDPC decoder starting from comparison between different techniques, different decoders parameters or standards, the effect of those parameters on the LDPC performance, also it discusses the algorithm selection process, and floating point implementation process.

Audio Transport in DisplayPort VIP

DisplayPort uses Secondary Data Packets (SDPs), which are transported over the Main-Link that are not main video stream data. This allows it to carry audio and video simultaneously. The VIP supports audio transmission both in the original mode as defined in the specification as well as just as any other SDP being transmitted.
