Thus the velocity of the Doppler processor output in (l,k)th channel should be calibrated according to the kth carrier frequency
For each of the pathloss models examined, it can be seen in Figure 4 that the higher the carrier frequency
, the large the additional gain required to maintain same pathloss as the 2 GHz carrier frequency
In order to facilitate research, the separation interfering induced by carrier frequency
offset can obtain as,
The FFT measurement of the peak value amplitude and frequency of the spike shows that the RF pulse begins with a carrier frequency
around 300 MHz.
At the transmitter, three wireless MIMO signals [MIMO.sub.1], [MIMO.sub.2], and [MIMO.sub.3] are generated and modulated using M-QAM at the same carrier frequency
[f.sub.c] = 2.4 GHz.
The SPWM FFT shows that the first two harmonics occur at 1000 Hz and 1100 Hz, centered around the carrier frequency
at [f.sub.c] [+ or -] 2 x [f.sub.1], where [f.sub.1] is the fundamental frequency.
Equation (1) shows that the complex propagation constant of the RF signal in soil is dependent upon the carrier frequency
, composition of soil, and soil volumetric water content.
where [[zeta].sub.n] is the phase of the transmitted symbol [a.sub.n] and [[OMEGA].sub.c] is the angular carrier frequency
offset given by [[OMEGA].sub.c] = 2[pi]T[f.sub.c], with [f.sub.c] and T being the carrier frequency
offset and the symbol duration, respectively.
offset arises when the oscillator at the receiver oscillates at a different frequency to that of the transmitter .
where S is the spectral emission mask attenuation in dB, [DELTA]f denotes the frequency offset from the center carrier frequency
, a represents the amount of relative PSD attenuation at [DELTA]f in the segment, and b is the relative PSD attenuation at the last [DELTA]f for the previous segment.
where m(t) is independent information stream with bit interval [T.sub.b], [[??].sub.c] = [[omega].sub.c] + [DELTA][omega] is the carrier frequency
, [[omega].sub.c] is the locally generated fixed reference carrier frequency
, [DELTA][omega] is the frequency offset, and n(t) is white Gaussian noise with power spectrum density [N.sub.0].
For example, the detection rate among Hispanic CFTR mutation carriers is approximately 57%, compared with approximately 80%-97% in other whites (4), whereas the Hispanic carrier frequency
of 1 in 46 is only modestly lower than that in Caucasians (1 in 29) (4).
