After the signal is time synchronized, the frequency-domain received signal preamble at th antenna can be expressed as (2).
In this paper, the MIMO cable is used to synchronize the frequency of the two source USRPs, as well as to achieve sample-level timing synchronization.
In order to synchronize the frequency, one node (e.g., destination) broadcasts a high-power reference signal to each source node and source node adjusts its frequency of oscillator to that of [6 8].
The lowered natural frequency synchronized with the frequency of the vortex shedding from the leading edge of the roof, which causes a negative damping effect of unsteady wind force.
Following further development of the concept and design of the iVLBI, as well as demonstration of its applications in science, the two-way method was recommended for synchronizing the reference frequency that was generated by the landing units (Kawano et al., 2009).
If the excitation is a broad-band process, the TMD tends to synchronize with the frequencies associated to the two translationally dominant modes of the structure.
We hypothesized that it may be possible to improve the effectiveness of rTMS treatment for resetting cortical oscillators by synchronizing the rTMS pulses to the frequency of the patient's individual alpha frequency (IAF), called synchronous TMS (sTMS) [ 10].
Each packet starts with a preamble which is used to synchronize the receiver with carrier frequency of the incoming signal, to find a good timing phase, and to identify the channel impulse response or to adjust a set of channel equalizer parameters.
The two ends of the measurement system were synchronized in frequency and phase thanks to the external reference of 10 MHz generated by rubidium oscillators and disciplined by GPS (Global Positioning System) receivers.
Although such methods provide a fast response to sudden frequency excursions, they tend to synchronize the loads and cause non-decreasing frequency oscillations [7].
The VCO output frequency is revealed to be synchronized with the reference frequency within the hold range.
