(battery) meets the requirements, it is more complex. Back to WEBRTC echo time-delay estimation, which is based on the Gips chief Scientist Bastiaan algorithm. Here is the main idea of the algorithm: Set 1 to say that there is a voice, 0 for no voice (mute or very weak sound), the reference Terminal (remote) signal X (t) and the receiving end (proximal) signal y (t) may be combined in the following ways: (0,0), (0,1), (1,0), (), (0,0) indicates that both the far end and the proximal side ar

LAN communication rate, the standard of WLAN is also developing continuously, the general trend is that the data rate is higher, the security is better and the quality of service is more and more guaranteed. And from the wireless LAN standards of the supporters and the geographical scope of use, wireless LAN can be said to have three camps: IEEE 802.11 series of standards, European hiperlan1/hiperlan2 and Japan's MMAC series standards. 802.11 series Standard In the 802.11 series, there are 4

provide broadband access. adsl/adsl2+ effective transmission distance of 5~6 km, ADSL downlink rate of up to 8Mbps, uplink rate of 640kbps, and adsl2+ downlink rate of the highest for 24Mbps, the uplink rate of 1Mbps. From the transmission rate, ADSL is difficult to meet the high bandwidth users access requirements, adsl2+ in the near future can basically meet the bandwidth needs, but the uplink bandwidth is low. Following the first generation of VDSL, the ITU passed the VD-SL2 in May 2005 (se

give up on it. For example, when a satellite is launched, the satellite operation monitoring system that displays the satellite track on the wall of the control Hall collects the operation parameters of the satellite in real time. After processing, it is displayed on the large screen in real time, this is a real-time system. However, real-time display of exceptions during satellite launch is not possible. The satellite track can only be interrupted when an accident (such as a rocket explosion)

feature vectors and Their transformed vectors are in the same straight line. The transformed vectors can be extended or shortened, or reverse, it even becomes a zero vector (the feature value is zero), for example. The feature value is the vibration spectrum. In addition to linear constants, another highlight is about vibration. In the Song Dynasty, China passed the opportunity to discover the matrix feature value theory. After Qin shaoyou threw a s

-technical professionals can understand the mysteries of this process. We start with the most basic concepts. One physical concept we all know is "electromagnetic spectrum ". This is the carrier of electromagnetic waves. It is produced by a relatively simple electronic device "oscillator. The oscillator emits a sine wave (remember this is the content of the high school ry class ?), Then we can adjust the oscillator to generate an electromagnetic wave

Style 5) QWindowsStyle:Microsoft Windows style6.2 Qt Style Sheets Qt style sheets are powerful mechanisms for customizing the appearance of components. The concepts, terms, and syntax of Qt style sheets are all inspired by HTML Cascading Style Sheets (CSS). However, unlike CSS, Qt style sheets are applied in the world of components.6.3 special effect form You can implement irregular forms, transparent forms, and other special forms to make the appearance of applications more personalized and at

instruments. The frequency of the 2 kHz-4 kHz part belongs to the intermediate frequency. If the frequency is too high, it will mask the speech recognition sound, especially when the 3 kHz is too high, which will cause auditory fatigue. The 4 kHz-5 kHz part is an on-site band that affects the definition of sounds such as language and instrument. By increasing this frequency band, people may feel that the distance between the sound source and the listener is slightly closer. The 5 kHz attenuatio

802.11n can deploy mobile applications with multiple requirements. It is also a mature milestone. Many customers are willing to deploy wireless networks on a large scale, or even replace Ethernet ). This expansion greatly increases the importance of wireless security and wireless security services to the business. VAR value-added dealers) and system integrators can leverage this market demand by providing more effective and more large-scale WLAN security solutions, including cloud-based services

China Unicom's "transfer via ticket" is the only effective solution to solve China Unicom's development dilemma. --> Currently, the discussion on China Unicom's predicament has always been a hot topic in the forum. Many of them say that mobile has a great advantage in low frequency, some people say that the problem of changing allocation alone can change the difficulty of China Unicom. I plan to analyze it. 1. Low Frequency Spectrum determines the

The whole process of speech enhancement, usually assumes that the noise is additive random stationary noise, and the speech is short and smooth, the following principles are described, are under these two assumptions to do. The entire speech enhancement process can be broadly divided into two partsFirst, noise estimationCalculation of attenuation factor (also called gain factor in some places)Finally, applying the attenuation factor to noisy speech, we can get the "pure speech" we expect. The ha

The receiver realizes the analog-to-digital transformation and sampling in the intermediate frequency part, and the sampled signal is multiplied with the number field, and the I and Q components of the baseband can be obtained. Each channel that uses a specific carrier frequency, code (spread code and scrambling code) and carrier relative phase (I or Q) can be understood as a class of physical channels when the wireless interface is transmitted.The spread sp
