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 ...

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 ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

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, ...

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 ...
