Figure 1 shows the workflow, which results in
modulation identification and classification.
Quadrature amplitude
modulation has a major application in various digital radio communications and data communications.
At 1 V forward voltage, the band simulations of three type
modulation structures are shown in Figure 5 [17].

modulation frequencies' ratio given by
To the best of the authors' knowledge, this paper is a maiden attempt to use an optical I/Q
modulation technique for MMF links based on direct detection for extending the transmission reach.
"The traditional 10 KHz audio bandwidth passes HD carriers present from 5 kHz to 10 kHz, wreaking havoc with
modulation readings," he said.
Many factors are considered to analyses performance of OEDM system such as number of subcarriers as well as IFFT/FFT point, number of phase sequences,
modulation scheme, type of channel, BER and etc.
Carrier based
modulation techniques are widely used in multilevel converters, since compared to space vector PWM strategy, this PWM strategy has the distinct advantage of ease of implementation.
