forward error correction scheme 1/5 Rake, Iowa

No bandwidth constant IEEE Trans. Most forward error correction correct only bit-flips, but not bit-insertions or bit-deletions.

Some of these terms and definitions are FECFRAME specific and are in line with [RFC6363]: Application Data Unit (ADU): The unit of source data provided as payload to the transport layer. These codes are efficient in terms of processing but not optimal in terms of correction capabilities when dealing with "small" objects. In particular, it defines the "FEC Framework (FECFRAME) FEC Encoding IDs" subregistry of the "Reliable Multicast Transport (RMT) FEC Encoding IDs and FEC Instance IDs" registry, whose registration procedure is IETF

One of the earliest commercial applications of turbo coding was the CDMA2000 1x (TIA IS-2000) digital cellular technology developed by Qualcomm and sold by Verizon Wireless, Sprint, and other carriers. The correcting ability of this FEC is: Up to 1 bit of triplet in error, or up to 2 bits of triplet omitted (cases not shown in table). Roca, et al.

This document assigns the Under-Specified FEC Encoding ID 130 under the ietf:rmt:fec:encoding name-space (which was previously assigned by [RFC3695], which is obsoleted by this document) to "Compact FEC" as specified in This can be achieved by means of a group key management protocol, or simply by pre-distributing the secret key (but this manual solution has many limitations). In the simplest form of FEC, each character is sent twice.

When m = 8, then S and E are equal. References to that specification should be replaced with references to this document. However, this padding does not need to be actually sent with the data to the receivers. These punctured codes (also known as "perforated" codes) are not as strong and cannot correct as many errors, but are more efficient and use less overhead than their half-rate counterparts.

Let e = (e_0, ..., e_{n-1}) be the corresponding encoding vector of n elements over GF(2^^m).

Procedures The algorithm defined in Section9.1. The FEC scheme with FEC Instance ID 0 MAY use the block partitioning algorithm defined in Section9.1 of [RFC5052] to partition the object into source blocks. Additionally, it uses the following definitions: Source symbol: unit of data used during the encoding process.
