DTW is mainly applied in the isolated word recognition algorithm, used to identify some specific instructions compared to good, the algorithm is based on DP (Dynamic programming) algorithm on the basis of the development. The introduction of speech recognition here first introduces the framework of speech recognition, first we have a comparison of the template sound, and then need to intercept it contains the part that really belongs to the voice, this is called VAD (voice activedetection) voice

We can see that color is formed by interacting with three elements: the light source, the reflective properties of the object, and the way the human retina and the visual cortex of the brain interact with light waves. No matter what media we use to work-painting, printing or networking-we all have to rely on the abov

Visual perception of all color image, all have lightness, hue and purity three kinds of nature, these three kinds of nature is the most basic element of color.
Lightness
In the absence of color, the highest brightness of the color is white, the lowest brightness of the color is black, there is a light from the dark gray series. In the color, any kind of purity has its own lightness characteristic. For example, yellow is the most obvious color, in the center of the
5G has high performance, low latency and high capacity characteristics according to 3GPP definition, and these advantages are mainly embodied in millimeter wave, small base station, massive MIMO, Full-duplex and beamforming technology.
Among them, massive MIMO and beamforming are closely related.

Remember the experiment of sunlight through a prism? The white light passes through the prism and is decomposed into a variety of colors that gradually transition to the color spectrum, followed by red, orange, yellow, green, green, blue, purple, and this is the visible spectrum. It is clear that the prism separates the mixed things.
Today's wireless network is like a bunch of white light, users do not see

Introduction to wireless network technology-Analysis of 4G stack system framework-4g stack system framework-this technology provides faster data rates and greater system capacity. The target peak speed is: 1 Gbps or more for low-speed mobile, hotspot coverage, and 100 Mbps for high-speed mobile and wide-area coverage. The above performance indicators mainly rely on two methods: Improving the spectrum efficiency and expanding the system bandwidth. To a
the connectivity of wireless signals, and whether the signal coverage and strength can meet user requirements. This requires on-site investigation. using various tools, the edge signal strength should be no less than 60%. The planning of wireless performance is actually a three-in-one plan of coverage, performance, and security. It is mainly about Whether AP's concurrency capability can meet the functional characteristics required by enterprises, and whether the distribution of AP dynamic ACL c
reaches several million times per second. For naked eyes, such flashing is invisible and can only be detected by the photosensitive receiver. In this way, the LED bulb can quickly transmit binary encoding.
The advantage of this technology is obvious: as long as you have a light bulb around you, you can get a wireless Internet connection. It is estimated that the number of bulbs in the world is about 14 billion.
Transmission speed up to 1 Gbps

the US Federal Communications Commission. It belongs to the industrial free radiation frequency band. The wireless LAN working in this band has two Spread Spectrum methods: Direct Sequence Spread Spectrum, DSSS) and Frequency Hopping Spread Spectrum Frequency Hopping Spread Sprectrum, FHSS.
In June 1997, IEEE passed the wireless LAN standard, namely the 802.11 s
The wireless mesh network is comparable to a small-sized Internet, which can better play a wireless role in enterprises. Then, the wireless mesh network is also combined with other technologies to play a more powerful role. The following is a detailed description of the knowledge of Wireless Mesh Network + cooperative relay technology.

The wireless TD-LTERelease8 version supports up to four downlink antennas for parallel transmission, which can reuse up to four data streams in space. In 20 MHz bandwidth, the peak rate of over Mbps can be achieved. In wireless TD-LTERelease10 and wireless TD-LTE-Advanced, the number of antennas supported by the downl

According to the latest GSA (Global mobile Suppliers Association) statistics, operators in 112 countries around the world have commercialized 331 LTE Networks. It is estimated that by the end of 2014, the number of Global LTE commercial networks will reach 350. With the arrival of the world's LTE construction wave, domestic operators have also accelerated the pace of LTE construction. Domestic LTE has two
Over the past few months, discussions have become increasingly enthusiastic about the evolution and deployment of 802.11ac. However, in consumer and enterprise-level markets, users' enthusiasm is not the same. 802.11ac has been widely supported in the consumer electronics industry. Apple, Samsung, HTC, Xiaomi, and many other mobile phone manufacturers have joined the ranks of 5G WiFi. However, for enterprise-level products, the promotion of 802.11ac seems to be slow.
