Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...

Error detection and correction has got a great practical importance in maintaining information (data) integrity across noisy channels. Convolutional encoding is ...

Until the last few years, the narrow bandwidth (300kHz) of the 950MHz radio channels, which was adequate for the audio and technical standards of the all-analog world, was insufficient to handle the ...

Frequency shift keying (FSK) is a popular digital modulation technique for data transmission. Some common applications of FSK modulation include both wired and wireless data transmission as well as ...

LTE networks and signals present a range of problems for the RF front end in handsets as the signal characteristics differ greatly from previous 2G and 3G standards. Key metrics such as battery life, ...

Portable wireless devices are becoming smaller, lighter, and more powerful with each new generation of cell phone technology. In the eyes of users, this trend is a wonderful addition. For designers, ...
