Complexity-Efficient LLR Estimation Using Piecewise Polynomial Fitting for LDPC Decoding in 100 Gb/S Bandwidth-Limited Flexible-Rate IM/DD System
We demonstrate a low complexity LLR estimation method based on piecewise polynomial fitting for LDPC decoding in 100 Gb/s bandwidth-limited flexible-rate IM/DD system, which reduces complexity by more than 90 % while maintaining almost equivalent performance.
