We review TCM with 16QAM constellations. Multiple state TCM widens design options and provides two additional settings for flexible transponders. 8-state TCM 12QAM increases transmission distance by 880km at 3b/s/Hz. TCM benefits substantially from BP.
In this paper, we propose a thin, flexible, polymer PTC sensor with a wide temperature measurement range. A polymer PTC sensor consists of several polymers and conductive filler and its resistivity changes with an increase in temperature. Conventionally, it has been proposed as a flexible temperature sensor. However, no research has yet achieved enough flexibility and a wide temperature measurement...
We demonstrated experimentally the improvement of the transmission distance by 27% of 150Gb/s signal at 3b/s/Hz with a novel TCM format, 8-state 12QAM TCM, compared to PM-8QAM. We also demonstrated improvement of the transmission distance for multiple state TCM using nonlinear compensation, ranging from 14% to 26%, while similar improvement was below 11% for PM signals.
We propose a new 4D coded modulation format, 64SP-12QAM, with same SE as PM-8QAM and straightforwardly-switchable with PM-16QAM. We experimentally demonstrated over 0.2 dB better sensitivity for 64SP-12QAM compared to PM-8QAM, enabling a transmission reach extension to 6,000 km at 6b/s/Hz.
We developed a magnetic resonance imaging (MRI) -detectable wireless flexible pressure sensor with pressure-sensitive LC resonator fabricated on a flexible film substrate. Measuring pressures in the body such as blood vessels and cardiac ventricle are very important in making diagnoses and in postoperative observation. However, conventional wired pressure sensors have difficulty in maintaining their...
We evaluated experimentally 2, 8, 32 state 32Gbaud TCM-QPSK and TCM-16QAM. TCM offers finer configuration for flexible transponders increasing SE, on 1.1dB wider ranges. TCM may also be used with HD-FEC in lower power transceivers.
We propose multi-redundancy optical coded modulation using superposed trellis. We experimentally prove that our scheme enables fine adaptive SE control and high coding gain of 7.1dB for 3-bit redundant 16QAM with quarterly reduced circuit complexity.
Measuring the local pressure in blood vessels is valuable in the postoperative monitoring of aneurysms. However, implanting a conventional pressure sensor equipped with power and signal cables causes difficulties during the operative procedure and carries a risk of infection after the implantation. In this study, we developed a wireless, implantable, and flexible pressure sensor. A magnetic resonance...
In this paper, we propose two methods to measure the semantic similarity for multi-lingual and short texts by using Wikipedia. In recent years, people around the world have been continuously generating information about their local area in their own languages on social networking services. Measuring the similarity between the texts is challenging because they are often short and written in various...
Metallic communication lines in wire communication systems are usually used as power lines. Ac communication signal and dc supply power are separated at input part of a powered terminal. Conventional well-known separators utilize the combination of inductors and capacitors. When the signal frequency is low, volume of these components increases. A conventional electronic choke circuit using transistors...
