Description: 此应用是为了使个人计算机的影音数据能很容易的透过WiFi 802.11 5G标准来传递具1080p的影音数据,同时利用泰发科技TF680的Full HD TV接收盒的解决方案提供一HDMI接口的影音信号给大尺寸的LCD TV,用以同步显示个人计算机端的影音数据. 如图(一)。
图(一) ：泰发科技TF-680 Wireless to 1080P Display解决方法
而TF-680 TV 接收端BOX之内部架构图如图(二)，主要是利用一WiFi Module将影音数据收集后由TF-680进行数字数据的解压缩后再进行影音数据的encode可支持RGB888或CCIR656，并且将音频数据及影音数据输入HDMI的Transceiver IC，为以输出标准的HDMI V1.3的信号给Full HD TV。
供应无线高清视频解决方案，芯片可实现蓝光高清信号wifi传输到HDTV，可实现PC2HDTV，还能达到networkKVM功能。欢迎致电0755-86299369，Q,1472007603-This application is to enable the personal computer video and audio data can be easily via WiFi 802.11 5G standard to pass a 1080p video and audio data, while taking advantage of Taifa technology TF680' s Full HD TV receiver box solution that provides a video signal HDMI interface to large-size LCD TV, personal computer terminal for simultaneous display of video data shown in (a). Figure (a): Taifa Technology TF-680 Wireless to 1080P Display solutions and TF-680 TV receiver BOX internal structure shown in Figure (b), mainly using a WiFi Module audio and video data collected by the TF-680 decompress digital data and then encode the video data to support RGB888 or CCIR656, and the audio data and audio data input for HDMI Transceiver IC, as the output of a standard HDMI V1.3 signal to Full HD TV.

Description: 于正交频分复用(OFDM)存在由带外辐射过高、峰均比(PAPR)过大等缺点，面向第5代移动通信(5G)的第3代合作伙伴计划(3GPP)的新无线空口(NR)标准，各大通信厂商都提出了包括滤波正交频分复用(Filtered-OFDM)、加窗OFDM、滤波器组OFDM(FB-OFDM)等新波形技术。考虑到5G更高的通信速率及带宽需求,并需适用于6 GHz以，上的高频通信(尤其是毫米波频段) ,5G候选波形需要更高的时频效率和更优的带外辐射特性,以满足5G通信的要求"。(Due to the shortcomings of orthogonal frequency division multiplexing (OFDM), such as excessive out of band radiation and high peak to average ratio (PAPR), new wireless air interface (NR) standard for 3G Partner Program (3GPP) of 5g mobile communication has been proposed by major communication manufacturers, including filtered OFDM, windowed OFDM, filter bank OFDM, etc. Considering the higher communication rate and bandwidth requirements of 5g, and being suitable for high frequency communication (especially millimeter wave band) above 6 GHz, 5g candidate waveform needs higher time-frequency efficiency and better out of band radiation characteristics to meet the requirements of 5g communication.)
