The FSK signals are modulated onto the power signal for transmission to the data reception station where they are demodulated and converted into a data form which is suitable for display. That minimises the errors which but for this could result in the alteration in the signals during ...
A method is disclosed for the reduction of the peak-to-average power ratio of a multicarrier signal. The method comprises the following steps: (a) detecting locations at which the amplitude of the signal is above a predetermined value; (b) applying a non-linear process, so that the amplitu...
We present the power spectrum of a sinusoidal carrier, frequency modulated by a random baseband pulse train in which the signaling-pulse duration is finite and the signal pulses may overlap and have different shapes. Symbols transmitted during different time slots are assumed to be statistically inde...
This measures the total power present in the channel bandwidth. Unlike a continuouswave (CW) signal, the power of a modulated signal is spread across a wide bandwidth. As a result, a complex integration is needed to calculate the total power of the channel. The PowerSuite channel power measu...
PROBLEM TO BE SOLVED: To provide a high efficiency power amplifier capable of generating an output signal of an inconstant amplitude with lower distortion and higher efficiency in an output band. SOLUTION: The power amplifier which receives a modulated signal and outputs a signal formed by amplifyin...
Received Signal Power is the normalized average power of the signal of interest (SOI) received at a ground station, which is influenced by the transmitted power and distance between the transmitter and receiver, as described in the provided text. ...
We generate a single-carrier 21.4-Gbaud polarization-division-multiplexed (PDM) 64-ary quadrature-amplitude-modulated (QAM) signal (256.8-Gb/s line rate) u... AH Gnauck,PJ Winzer,A Konczykowska,... - 《Journal of Lightwave Technology》 被引量: 94发表: 2012年 An I/Q-Channel Time-Interle...
An electrical signalling apparatus including a transmitter and receiver connected to the same electrical power distribution network wherein a signal generated by the transmitter is used to control apparatus connected to the receiver. The system uses a pair of amplitude- modulated low frequency signals ...
The envelope (iv), (v), and (vi) of JM signals is the combination of three different QAM signals with continuous wave signals. The average area is the average of envelopes of each modulated signal. c The peak-to-average power ratio (PAPR) under different power ratios of continuous wave ...
An 85 GHz input signal is modulated by a differential pair, and a push-push frequency doubler with capacitive degeneration technique is designed to obtain the 170 GHz modulated output signal. Via the use of negative impedance to eliminate the leakage current of transistors, the proposed enhanced ...
