Abstract: At a receiver side, to enhance the performance of concatenated LDPC and TCM coding, an iterative decoding between TCM decoder and LDPC decoder enables improvement in the reliability of received LLRs of each symbol after each iteration. A SOVA output of the TCM is used for LDPC decoding, and then the updated LLRs from LDPC decoder are further looped back to the TCM decoder for the next iteration. In such a manner, the decoding performance could be significantly improved after just several iterations.
Abstract translation: 在接收机侧，为了提高级联LDPC和TCM编码的性能，TCM解码器和LDPC解码器之间的迭代解码器能够在每次迭代后提高每个符号的接收LLR的可靠性。 TCM的SOVA输出用于LDPC解码，然后来自LDPC解码器的更新的LLR进一步循环回TCM解码器进行下一次迭代。 以这种方式，在几次迭代之后，解码性能可以显着提高。

Abstract: Methods and systems for Brillouin optical time-domain reflectometry include optically filtering out non-Brillouin signals reflected from a fiber. Brillouin signals reflected from the fiber are coupled with a local oscillator to produce a Brillouin shift signals. The Brillouin shift signals are converted to an electrical domain using a photodetector. The electrical Brillouin shift signals are converted to a digital domain using a low-speed analog-to-digital converter that has a sampling rate below a Nyquist rate sufficient to fully resolve the electrical Brillouin shift signals.
