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 ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Validation of the derived analytical bound for the MAA-GSM-LD scheme using Monte Carlo simulation results. 4. Proposal of a scheme called GCQSM-LD that extends the MAA-GSM-LD scheme into the C-QSM ...

Derivation of an upper bound average bit error rate (ABER) expression for the GQSM-H-8QAM scheme over independent and identically distributed (i.i.d) Rayleigh ...

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 an ideal world, a 16-bit, 20 GSamples/s digital-to-analog converter (DAC) would generate accurate RF signals for a variety of modern communications protocols. However, ASICs with this kind of ...

In the late 1970s, television de- modulators became available with synchronous detectors, providing a method of monitoring the in-phase and quadrature signal components of television transmitters.

The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...

Broadband communications equipment is increasingly pushing the envelope of mixed-signal technology in terms of speed, distortion, signal-to-noise ratio (SNR), and cost. Many broadband wireless systems ...
