With the development of the communication network towards broadband and mobile, the optical fiber wireless communication system (ROF) integrates Optical Fiber Communication and wireless communication, giving full play to the advantages of broadband and anti-interference of optical fiber lines, at the same time, it makes full use of the convenient and flexible wireless communication to meet people's needs for broadband. Early ROF technology was designed to provide high-frequency wireless transmis

With the rapid development of wireless communication technology, spectrum resources, especially those under 3 GHz, become increasingly tense. Due to the emergence of Wireless LAN technology and wireless network technology, more and more people are using these technologies to connect to the Internet and telecommunication networks wirelessly. Most of these technologies use non-authorized frequency bands to make these frequencies saturated. However, some

During the course of study, this parameter is often used. Later I worked mainly on audio/speech codec, but the concept of cepstrum was rarely used. I saw these words when I read a paper today, I think it is very practical. Let's review this signal feature. Time-cepstrum analysis is very effective when extracting the signal characteristics transmitted by the carrier. Cepstrum is widely used in the extraction of Speech Recognition feature parameters. This is because the essence of speech is the

Summary Starting from the analysis of GSM spectrum efficiency, this paper analyzes the loss of spectrum efficiency of voice service after the GSM network is upgraded to GPRS, and the new data service access ability, and finally takes into account the maximum access ability of the integrated service under GSM current spectrum from the mutual substitution between

to implement spectrum analysis or other work on the computer. The computer's requirement for signals is that both the time domain and frequency domain must be discrete and must be finite. While Fourier transform (FT) can only process continuous signals, DFT is born in response to such a need. It is the representation of Fourier transformation in discrete fields. However, in general, the calculation of DFT is very large. Before the first high-speed Fo

FFT (Fast Fourier transformation) is a classic algorithm used for digital signal processing. Many people who have studied DSP or chip design know this algorithm. However, have you ever wondered why there are so many FFT operations in digital signal processing? Some may say that in order to analyze the signal spectrum. The problem below is to analyze the daily needs of the spectrum, such as mobile phone call

Photoshop tools and plotting I. Photoshop plotting tools Photoshop has many drawing tools, including paint brushes, pencils, history paint brushes, art history paint brushes, photo and leather stamps, pattern stamps, Erasers, background erasers, Magic Erasers, blur, sharpen, smear, deepen, fade, and tools such as sponge. Ii. Set the paint brush When using

This tutorial is for beginners, and I include creating new brush presets and how to use pen tools. You will have more opportunities to practice layer blending mode, filters and free transform tools. Try! Step 1 Create a new document, fill the black background, wide, set to 980*400px, and then you can change this setting, using Pixel/inch because the image created is used for the Web page. Now, I create a brush preset to do this, the first step is to select the Brush tool, from the

, the color of this work is the golden System, gold for beginners is more difficult to grasp a hue. First contact is easy to do with the green or red. It is rare to encounter such a gold tone case, why don't we take to analyze and record its use of color: For such a bad grasp of the color, we can record its color value, but also in the color spectrum to choose its different lightness of color, to see the basis of deeper and lighter colors

The features of the four wireless extended communication technologies are completely explained. First, let everyone understand the features of the wireless extended communication technology, and then fully introduce the features of the wireless extended communication technology. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. The so-called spread-spectrum communica

The principle of PN Code synchronization in 1.CDMA system The transmitter and receiver adopt high accuracy and high stability clock frequency source to ensure the stability of frequency and phase. But in the practical application, there are many uncertain factors, such as the instability of sending and receiving clocks, uncertainty of launch time, transmission delay and interference, especially in mobile communication, these uncertainties are random, can not be compensated in advance and can on
