Overview

Viterbi encoding is widely used for satellite and other noisy communications channels.
There are two important components of a channel using Viterbi encoding:
the Viterbi encoder (at the transmitter),
the Viterbi decoder (at the receiver).
A Viterbi encoder adds extra information in the transmitted signal to reduce the probability of errors in the received signal that may be corrupted by noise.
A Viterbi decoder performs a maximum likelihood detection of 1 bit data transmitted over a channel with inter-symbol interference (ISI). The 1-bit data to be transmitted is encoded with an n-bit convolutional code in the convolutional encoder.

Key features

  • Decoding of convolutional codes,
  • Hard Decision Decoding,
  • Trace-back method for survivor memory,
  • Parameterized architecture allows for customization of the following functions:
    • Convolutional code definition parameters: code rate, code generation vectors, code constraint length.
    • The survivor memory word length (RAM)
    • The initial path metric for state 0,
    • Parallel or serial (reverse or correct order) data output format.

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.
