Title: Wavelength conversion device and preparation method therefor, and laser-fluorescence conversion type light source
Inventor: TIAN ZIFENG
IPC: F21V13/00
Filed: 2017-12-06
Abstract: Provided are a wavelength conversion device and a preparation method therefor, and a laser-fluorescence conversion type light source. The wavelength conversion device comprises an alumina substrate layer, a silver reflective layer and a luminescent glass layer which are sequentially stacked. The silver reflective layer reflects light emitted from the luminescent glass layer. The wavelength conversion device further comprises a glass protective layer arranged between the silver reflective layer and the luminescent glass layer. The refractive index of the glass in the glass protective layer is lower than the refractive index of the glass in the luminescent glass layer, and the glass protective layer does not cause a color change reaction with silver. The laser-fluorescence conversion type light source comprises a laser device and a wavelength conversion device. By providing the glass protective layer which separates the silver reflective layer and the luminescent glass layer, the reflection effect and the luminance can be further improved, the color change reaction between the silver reflective layer and the luminescent glass layer is avoided, and higher luminous efficiency and luminescence saturation can be achieved.

Abstract: Divers aspects de la présente invention concernent un rapport de marge de puissance amélioré (PHR) permettant de fournir une rétroaction de mise à l'échelle de puissance de signal de référence de sondage (SRS) ayant subi une formation de faisceau. Le SRS ayant subi une formation de faisceau le long de directions dans lesquelles un équipement utilisateur (UE) est le plus apte à annuler le rapport signal d'interférence/brouillage de liaison descendante (DL) sur interférence plus bruit (SINR) serait très utile pour la formation de faisceau DL. La formation de faisceau de SRS nécessite un support supplémentaire, si des décisions relatives au rang sont prises au niveau de l'eNB. Par exemple, des facteurs de normalisation de puissance doivent être envoyés ou notifiés sur la liaison montante (UL) à l'eNB. La présente invention concerne des exemples de la manière dont le PHR sur la liaison montante peut être utilisé pour effectuer une telle notification. Deux types de PHR sont proposés, l'un nominal pour le SRS orienté UL, comme le PHR de type LTE, et l'autre pour le SRS orienté DL où l'UE signale ou indique également les facteurs de normalisation de puissance de chaque port SRS.

Title: Ofdm channel training authentication method based on independent check coding
Inventor: REN PINYI
IPC: H04B17/391
Filed: 2018-08-06
Abstract: An OFDM channel training authentication method based on independent check coding. The method is used for preventing interference, zeroing and cheating risks suffered by pilot frequencies. The pilot frequencies are randomized, are inserted into subcarriers and are coded to correspond to subcarrier activation patterns (SAPs). Although the coded SAPs are masked by malicious signals, the coded SAPs may be identified and decoded into original pilot frequency signals and are further used for high-precision channel impulse response (CIR) estimation, thereby successfully solving the problem of channel estimation in a pilot frequency attack environment. In the present invention, subcarrier coding and channel estimation are combined, and high-security and high-stability wireless channel training authentication is implemented in an attack environment by means of bit rate optimization and channel estimation.
