Dec 22, 2023 · A pivotal decision in FEC coding and decoding involves choosing between Hard-Decision FEC (HD-FEC) and Soft-Decision FEC (SD-FEC). HD-FEC makes binary decisions based on exact thresholds, determining whether 1s or 0s have occurred, while SD-FEC makes decisions based on probabilities, assessing the likelihood of a 1 or 0 occurrence.
Turbo coding is an iterated soft-decoding scheme that combines two or more relatively simple convolutional codes and an interleaver to produce a block code that can perform to within a fraction of a decibel of the Shannon limit.

Apr 4, 2019 · Pre-FEC BER threshold— A predefined threshold for error-free post-FEC transmission determined by NCG; Other considerations include hardware complexity, latency, and power consumption. One major decision point for FEC coding and decoding is between Hard-Decision FEC (HD-FEC) and Soft-Decision FEC (SD-FEC).

One of the main advantages of Cisco SD-WAN is that it can use a mix of any available transports at any location in an active-active fashion. This typically means that organizations wanting to lower costs chose to utilize many Internet links including LTE 4G/5G over expensive leased lines and MPLS circuits.
