چکیده
We experimentally demonstrate a rate-adaptive concatenated forward error correction (FEC) scheme to minimize the information rate loss due varying channel conditions. The coding is based on inner soft-decision polar code and outer hard-decision staircase code. An experiment in wavelength-division multiplexed (WDM) system with different SNR per WDM performed by employing codes various coded modulation schemes over target distance of 140km which relevant for extending reach data center interconnects. Experimental results show that achieved can be improved up 37.6% proposed w.r.t. fixed ZR FEC.

Single-Trial Adaptive Decoding of Concatenated Codes
In this paper decoding of a concatenated code is considered. We use a Bounded Minimum Distance (BMD) decoder for the inner code correcting up to (d − 1)/2 errors and a Bounded Distance (BD) decoder for the outer code, which corrects ε errors and τ erasures if λε + τ ≤ d − 1, where a real number 1 < λ ≤ 2 is the tradeoff rate between errors and erasures for this outer decoder. Here d and d are t...
متن کاملRate-compatible punctured serial concatenated convolutional codes
In this paper, we propose and compare some good rate-compatible serial concatenated convolutional code (SCCC) families. To obtain rate-compatible SCCCs, the puncturing is limited to inner coded bits. However, and this is the novelty proposed in this paper, we do not limit the puncturing to inner parity bits only, but we extend it also to inner systematic bits, thus obtaining higher rate SCCCs (...

Forward error correction (FEC) is as one of the key technologies enabling the next-generation high-speed fiber optical communications. In this paper, we propose a rate-adaptive scheme using a class of generalized low-density parity-check (GLDPC) codes with a Hamming code as local code. We show that with the proposed unified GLDPC decoder architecture, a variable net coding gains (NCGs) can be a...
متن کاملNew high-rate convolutional codes for concatenated schemes
This paper considers the use of the best high-rate k/(k+1) convolutional codes obtained using the new construction technique described in [1] in a concatenated scheme. Simulation results for an AWGN channel and for a realistic magnetic recording channel are reported. It is shown that these codes, endowed with a decoding algorithm working on the dual code, yield performance improvements over the...
