carrier wave

n.
An electromagnetic wave that can be modulated, as in frequency, amplitude, or phase, to transmit speech, music, images, or other signals.

carrier wave

n
(Electronics) a wave of fixed amplitude and frequency that is modulated in amplitude, frequency, or phase in order to carry a signal in radio transmission, etc. See amplitude modulation, frequency modulation

Another major problem in acoustic channels is high delay links in comparison to the electromagnetic channels which have carrier waves with speed similar to the light speed (3 x [10.sup.8] m/s).
My interest in this debate first took root when I heard scientists and engineers talk about carrier waves and the embedded information.
Envelope waves tend to move in slower velocity than the carrier waves. Therefore, [xi] and [tau] are called slow variables transformed from the fast variables x and t by the following relations,
Three 20MHz carrier waves in the 1800MHz, 2100MHz and 2600MHz frequency bands were combined using new radio network technologies such as 4x4 MIMO (Multiple Input Multiple Output), and higher order modulation (256-QAM).
The time-varying expressions for reference and carrier waves can be mathematically represented as follows,
The PTA official said while commenting on the said activity, The Cordless DECT phones are high frequency devices and cause noise and interference in communication and deter the signals due to overlapping of carrier waves. PTA had received many complaints from telecom service providers and the consumers on this issue and upon deep examination the decision was made for larger benefit".
This method involves comparing a sinusoidal signal also called modulating waveform with triangular signals or carrier waves. The switches of each leg require (m-1) triangular signals having the same frequency [f.sub.p] and same magnitude [A.sub.p] [14], figure 2.
DMT divides the data into multiple subcarriers (carrier waves), and multi-level modulation is used for each subcarrier to achieve high transmission speeds (Figure 2).
To get further redundancy in the sorting process, more DC-sources may be connected to the CHB-MLI while keeping the number of carrier waves fixed.
This solution is completely different from Equation (3), and consists of an envelop and carrier waves, the former is [phi](x, t) = [A.sub.0] sec h {[A.sub.0][square root of (bm) [(x-[x.sub.0]) - vt] / h} and a bell-type non-topological soliton with an amplitude [A.sub.0], the latter is exp{i[mv(x - [x.sub.0]) - Et]/ h}.
The Chip operates at a much higher frequency and generates random waves, which becomes the carrier waves over the constant Microwaves emitted from Mobile Phones, Computers and other Wi-Fi devices and makes it compatible with the body's random waveforms.
Moreover, we assign the respective spatial and temporal coordinates for the envelope and carrier waves. We use x and t as the spatial and temporal coordinates, respectively, for describing the carrier wave.
