CML Microcircuits announced the introduction of the CMX7146, a flexible data modulator that simplifies the design of transmit-only solutions using BPSK (binary phase shift keying) and differential ...
In the last years, a major transition from analog to digital modulation techniques has occurred and it can be seen in all areas of wireless communication, satellite and cellular systems. This paper ...
Free Space Optics is the technology which implies the line-of-sight link for the transfer of data between two distant points. The beam of light is used to provide optical connection that can transmit ...
On July 25, 2015, China launched two modernized BeiDou satellites. Although the nomenclature is still uncertain, the Joint Space Operations Centre / North American Aerospace Defense Command ...
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 ...
With wireless LAN (WLAN) popularity continuing to soar, designers must now begin evolving this to the 5-GHz band. Making this leap will not be easy. The IEEE 802.11a system calls for 5-GHz WLAN ...
Binary FSK(Frequency Shift Keying) and PSK(Phase Shift keying) are extensively used in telecommunication for digital data transmission. FSK/PSK modulator circuits usually employ analogue components ...
Internet from space via satellite has become a topic of interest. Commercial satellite networks, such as SpaceX Starlink and Telesat LightspeedTM, aim to provide high-speed Internet to remote and ...
A-BPSK aviation binary phase shift keying—a form of phase-shift keyed modulation with shaped filters especially adapted to perform in an RF environment subject to fading A-QPSK aeronautical quadrature ...
