If we can adopt equally spaced (equi-distant) pilot symbols with equal power for channel estimation and symbol detection, then it can be analytically shown that the channel mean-squared estimation error [1, 3] as well as the BER [7] are minimized, while the lower bound on channel capacity [8, 9] is maximized.
The struggle for equal rights and equal power for women is opposed not only by laws, institutions, and practices but also by sexual desire itself.
The equal power allocation allocates equal power for each subchannel, while the proposed algorithm performs an optimal power allocation with the consideration of imperfect spectrum sensing, cross-tier interference, and QoS requirements.
One of the most popular excitation methods for modal testing of rotating machinery is known to be the uncorrelated isotropic excitation, which requires two independent random sources with equal power for generation of a pair of uncorrelated excitation signals.
It is noted that the assumption of equal power for all channels used in (23) is not true for the real signals recorded by the AVS unit, but these can be calibrated in practice [15].
In this work, a new excitation method, the modulated random excitation, is proposed such that a pair of random signals with equal power for modal testing of anisotropic rotors can be effectively generated by modulating the random signal from a single random source with two harmonic carriers of a frequency with 90° phase difference.
In our work, we found that certain web queries on influenza follow the same pattern as that obtained by the two other surveillance systems for influenza epidemics, and that they have equal power for the estimation of the influenza burden in society.
It is found that the BEP performance of the two ordered best relays distributed BF with equal power allocation for AF (at high SNR) and DF (for all SNRs) schemes outperforms the BEP performance of the best ordered relay alone.
For equal powers and completely uncorrelated speckle patterns, the SNR should increase with the square root of the number of averages.
Also, we perform equal power allocation for all the algorithms.
