Initial synchronization assisted from inherent diversity on LTE sector search process

Estimations of time error and frequency offset upon initial synchronization are investigated in this paper as components of the sector search process in third-generation partnership project (3GPP) long-term evolution (LTE) communications. The proposed system considers intercell interference, inter-carrier interference and…

Regularizing DNN acoustic models with Gaussian stochastic neurons

Dropout and DropConnect can be viewed as regularization methods for deep neural network (DNN) training. In DNN acoustic modeling, the huge number of speech samples makes it expensive to sample the neuron mask (Dropout) or the weight mask (DropConnect) repetitively from a…

Optimal bandwidth design of laser radar receiver

To improve the sensitivity of a car laser radar, the method of transmitting encoded signal has been discussed. However, for laser radar that transmits encoded signal, the bandwidth of transimpedance amplifier (TIA), which is used to transform current signal generated…

Sparse Density Estimation on the Multinomial Manifold

A new sparse kernel density estimator is introduced based on the minimum integrated square error criterion for the finite mixture model. Since the constraint on the mixing coefficients of the finite mixture model is on the multinomial manifold, we use…

Reliability Analysis of Highly Redundant Distributed Storage Systems with Dynamic Refuging

In recent data centres, large-scale storage systems storing big data comprise thousands of large-capacity drives. Our goal is to establish a method for building highly reliable storage systems using more than a thousand low-cost large-capacity drives. Some large-scale storage systems…
