identification is an important function for an intelligent receiver.
QAM is a widely used higher order modulation
Based on the SOI PIN electro-optic modulation
structure, a micro-nano Si/SiGe/Si double heterojunction electro-optic modulation
structure is presented, which is abbreviated as Silicon/Silicon Germanium/Silicon-On-Insulator (Si/SiGe/ Si-OI) structure, as shown in Figure 1.
[9, 10], the aim of this present paper is to continue the investigation of the influence of gravitational modulation
on convective instability in porous layer heated from below, by assuming that the modulation
is with two frequencies.
With the advancements in laser source technology, the directly modulated VCSELs have become the most preferable laser source for short-range applications due to their attractive attributes, for example, low manufacturing cost, low drive voltage, high modulation
bandwidth, low power consumption, and capability of array integration .
"The carrier level in traditional AM broadcasting is constant, and is used as the reference level to determine the modulation
of audio being broadcast," said Mark Grant , CEO of Belar Electronics.
In the SPS-SLM based OFDM transmitter, the random binary data is considered as input data sources that are converted into symbolic form according to the modulation
Next, the reconfigurations of the gate signals are presented for the discontinuous pulse width modulation
In the communication transmission technology, modulation
classification for communication signals is an important research direction, especially in the field of space communication, satellite communication, underwater communication, and so forth.
