Abstract

. We propose a technique for simultaneously transmitting two signals with different waveforms, non-return-to-zero on-off keying (NRZ-OOK) signal and discrete multitone (DMT) signal, in an optical wireless link based on visible light emitting diode (LED). A sparse compressive sampling technique is proposed to reduce the length of the DMT signal encoded by quadrature phase shift keying (QPSK) symbols and a derivative-subtractive sampling is proposed to separate the NRZ-OOK signal and the DMT signal from the mixed signal (NRZ-OOK + DMT). It is possible to reduce the length of the DMT signal up to 38% using the sparse compressive sampling technique. A 37.6-Mb/s transmission capacity (NRZ-OOK: 10 Mb/s, QPSK symbols: 20 Mb/s + 7.6 Mb/s) is achieved over 10-MHz bandwidth.

基于稀疏压缩采样和导数-减法采样的开-关键离散多音信号可视LED无线同步传输

.我们提出了一种在基于可见光发射二极管（LED）的光无线链路中同时传输具有不同波形的两个信号的技术，即不归零开关键控（NRZ-OOK）信号和离散多音（DMT）信号。提出了一种稀疏压缩采样技术来减少由正交相移键控（QPSK）符号编码的DMT信号的长度，并提出了导数减法采样来从混合信号中分离NRZ-OOK信号和DMT信号（NRZ-OOK+DMT）。使用稀疏压缩采样技术可以将DMT信号的长度缩短至38%。在10MHz带宽上实现了37.6Mb/s的传输容量（NRZ-OOK:10Mb/s，QPSK符号：20Mb/s+7.6Mb/s）。

期刊介绍： Since 1992, the Radioengineering Journal has been publishing original scientific and engineering papers from the area of wireless communication and application of wireless technologies. The submitted papers are expected to deal with electromagnetics (antennas, propagation, microwaves), signals, circuits, optics and related fields. Each issue of the Radioengineering Journal is started by a feature article. Feature articles are organized by members of the Editorial Board to present the latest development in the selected areas of radio engineering. The Radioengineering Journal makes a maximum effort to publish submitted papers as quickly as possible. The first round of reviews should be completed within two months. Then, authors are expected to improve their manuscript within one month. If substantial changes are recommended and further reviews are requested by the reviewers, the publication time is prolonged.
