Sentence examples for imperfect estimation from inspiring English sources

However, the feedback delay of CSI estimates has a similar model as for the imperfect estimation.

However, in practice, the channel vectors are estimated from training sequences and, inherently, this leads to imperfect estimation.

Hence, the achievable rates for the imperfect estimation are close to the perfect cases.

Imperfect estimation of the channel matrices is still a major drawback in the proposed CF protocol with massive MIMO.

The imperfect estimation brings out the residual interferences, and the BER curve suffers a floor at high.

The state represented by an agent at each iteration of the Q-learning algorithm is actually an imperfect estimation of the environment state.

Obviously, if the estimations are perfect, the interference can be effectively eliminated; otherwise, the imperfect estimations may result in the residual interferences.

We are the first to report on age and gender trends of suicide in Sri Lanka having adjusted for the imperfect estimations of different age and gender population figures (see Additional file 1).

Imperfect channel estimation (channel estimation error) has been studied in [35, 36], where it has been shown that there exists a statistical lower bound on the variance of estimation error that allows operation with no network coding error.

Furthermore, imperfections like additive noise, an imperfect channel estimation, errors accumulated during successive interference cancellation and a non-ideal projection of the constellation into the orthogonal subspace of interference are assumed in this simulator.

The model of the imperfect channel estimation in [13] is employed, and the channel estimation error refers to the normalized one by the mean channel gain.
