15, the amplitude modulation
term [m.sub.a] is considered equal to 0.9 and the frequency modulation term [m.sub.f] is accommodated correspondingly.
The extent of information leakage caused by amplitude modulation
could be measured and processed more easily through an ISO 14443 compliant reader demodulation process without any EM probe or additional hardware filter.
If the amplitude term VP is varied, the resulting modulation is called as Amplitude Modulation
(AM), if f term is varied, the resulting modulation is called as Frequency Modulation (FM), and if F is varied, the resulting modulation is called as Phase Modulation (PM).
For conventional amplitude modulation
, there is a one-to-one relationship between the [2.sup.m] channel waveforms and points on the real line.

It is also the first modem of its kind to support 6x carrier aggregation (CA) and 256-QAM (Quadrature Amplitude Modulation
) scheme making it better than what either of its competitors has to offer (Snapdragon 845 and Kirin 970).
Furthermore, the technology supports 4x4 MIMO (Multiple-Input, Multiple- Output) and higher-order 256 QAM (Quadrature amplitude modulation
) scheme to maximize the data transfer rate.
The systematic error of measurements depends on all three amplitude modulation
parameters: amplitude, frequency and phase (with respect to the start of acquiring the series of samples).
Quadrature amplitude modulation
(QAM) is a popular protocol that encodes information as a combination of amplitude and phase values.
In the first scenario, 2.4 Tbit/s with 16QAM (Quadrature Amplitude Modulation
) was achieved over a transmission distance exceeding 300 km.
It adds higher order modulation in the form of 256 quadrature amplitude modulation
(QAM), providing an additional 33- percent improvement in data rate.
Optically-induced amplitude modulation
(AM) of mid-infrared lasers was realized by researchers at Stevens a few years ago, but AM signals are at the mercy of dust and fog.
