To assistance of several multimedia services, have higher data rate to wireless communication system. The necessity of high bit error rate (BER) wireless communication with high channel capacity and reliability, multiple-input multiple-output (MIMO) system is a desired method. In the multifunctional wireless communication application, MIMO antenna system should have compact structure and high isolation [2]. Numerous technique have been proposed…

(for example by a bathrobe or a blanket), the system fails to work. There are other disadvantages of the IR-based solution: for example the transmitters tend to consume a lot of power so battery life is shortened if transmissions are frequent. • Network-based methods i) IEEE 802.15…

in wireless communication systems can suffer from data losses due to multipath propagation, further leading to intersymbol interference. These conditions compromise the integrity of the information transmitted. This paper explores the Viterbi algorithm used to combat error bounds in convolutional codes, and develops a MATLAB-based alternative model of the algorithm for continuous time applications that is shown to significantly diminish the effects of intersymbol interference in the wireless…

devices during classes has been a discussed issue for long, because of problems regarding the safety of the wireless connection, the costs of using these kind of devices for learning institutions and the personal use each student does with them. Many researchers argue that technologies used during lectures are only damage for students, because they tend to pass their time on social networks or surfing in Internet rather than follow the lesson. According to Dr. Claire La Roche and Dr. Mary…

Assignment 2 Data Communication- Net Centric Question 1 CDMA is what that have a several protocols that was used in the 2G and 3G wireless communication. CDMA is a service that provide all the communication overall and it also provide in major service in network capacity. CDMA service is mostly used in Cell phone and it can be easily be used for communicating terminal with two base stations. CDMA is a form of multiplexing, which allow a number of signals to work on a single transmission…

We are aiming to develop a device which is useful for both deaf and dump. We introduce a new device “SILENCE BREAKER”. It consist of a Camera, Micro Projector, Mobile computing device and a bluetooth headset. The synchronized action of all these components helps the dump and deaf for proper communication. The Silence Breaker recognizes the gestures of the dump and generates voice signal corresponding to it. In the case of deaf, the device captures the oral sounds and converts to gestures which…

with friends or families. Also, a type of technology that is used frequently is the Internet. The Internet allows people to connect with people and can gain facts that are essential for people to live. Nurse uses technology such as the Internet and wireless devices to communicate in their field. Also, it makes nurses life’s easier than tracking down a colleague to know what to do if something terrible happens such as someone falling of the bed. Besides making the nurses life easier, the…

not have to read lips all the time. They are one of the big reasons why technology has advanced so much in the deaf community. Wireless Telecommunications Bureau is responsible for all FCC wireless telecommunications programs and policies. These services include amateur radio, cellular networks, and many other wireless networks. These workers are to watch over every wireless communication and make sure everything is in check. They have to make sure the programs are up to date and appropriate for…
