Nonlinear Noise Compensation in an Integration System of Fiber-Wireless Communication and Free Space Optical Communication by Long Chen, Miao Liu, Zhijun Tang

“…Up to 1-Gbaud 16QAM discrete multitone (DMT) OFDM signal can be first transmitted over the distance of 100-m single-mode fiber (SMF), then delivered over the distance of 100-m FSO link, and finally, transmitted over the distance of 4 m wireless. The bit-error-ratio (BER) of the OFDM signal in the integration system can be less than the hard-decision forward-error-correction (HD-FEC) threshold of 3.8 × 10−3. …”

OCT-Precoding Combined with LDPC-Coding Scheme for 128 QAM MB-OFDM UWBoF System by Changqing Xiang, Xi Yang, Xiaojun Zhu, Qiong He, Renmin Zhang, Zhiyang Xiang

“…The simulation results showed that compared with the traditional scheme, the receiver performance of this scheme was improved by 2.7 dB when the LDPC-coding rate was 87.5% through 70 km standard single mode fiber (SSMF) transmission and the bit error rate (BER) was 3.8 × 10−3. Besides, the constellation distribution was more convergent and uniform.…”

Capacity Estimation of the Very Short-Range Electromagnetic Underwater Channel Based on Measurements by Jesús López-Fernández, Unai Fernández-Plazaola, Jose F. Paris

“…For example, they are negatively affected by factors such as mechanical noise, slow propagation speed, and, particularly, low bandwidth, which leads to digital links at a lower bit rate. However, in short-range links, these problems can be overcome by reconsidering the use of electric current communications. …”

Hybrid Single-Packet IP Traceback with Low Storage and High Accuracy by Ming Hour Yang

“…RIHT uses IP header’s ID and offset fields to mark packets, so it inevitably suffers from fragment and drop issues for its packet reassembly. Although the 16-bit hybrid IP traceback schemes, for example, MORE, can mitigate the fragment problem, their storage requirement grows up with packet numbers. …”
