In recent years, there are some new research results about signal injection including the improvement of the fundamental signal power of TWT by harmonic injection [4, 12], the harmonic and intermodulation distortions associated with two-tone modulation , the suppression of IMD3 by harmonic injection , and the particle swarm optimization algorithm (PSO) which are applied to suppress IMD [15,16].

Such two-tone modulation is important for several applications, such as multichannel RF-frequency division multiplexed transmission of analog or microwave signals .
In Section 4, we present the simulated IM and FM responses and noise characteristics under single- and two-tone modulations. Finally, the present work is concluded in Section 5.
A creepy carousel, first met in darkness, it periodically lights up and revolves, the bulbs on its ogee arches flashing in varying sequences, an automated drum kit that rides it beating time for the broadcast of a wheezy two-tone modulation
on what sounds like the traditional carnival harmonium.
In Figure 4, the Cartesian loop deals with two-tone modulation
In contrast to the large peak-to-average values characteristic of two-tone modulation
and more complex signals, CW signals encompass phase, frequency, or amplitude-modulated carriers.
The input is of a two-tone modulation
with the following specifications: K[Alpha] = -0.1 adaptation rate and K[Beta] = -0.01 adaptation rate.
