... is less of a correlation. Index Terms — adaptive coding, correlation, predictive The advantages of the proposed prediction scheme are coding, speech processing, signal to noise ratio obvious: (i) all Lp predictors are predetermined, i.e. there is no need to transmit the coefficients, as these are stored at the ...

... 4G systems such as randomness in traffic and channel propagation models. In LTE-Advanced [6-7]. At its core, 802.16m uses time-tested these networks the signal to noise ratio of received signal technologies such as Orthogonal Frequency Division changes dynamically, which in turn switches to more or less Multiplexing (OFDM), Orthogonal Frequency Division ...

... at low slip motor, thereby determining its condition. Various IMs based on the current signal analysis, detection based on variables are measured, such as: acoustic noise, vibration signals attracts much less attention. In the current paper, detection of the broken bar was conducted by observing electromagnetic field, air-gap torque, voltage ...

... the Histogram of Oriented Gradients (HOG) method is refined. Since the pixels with low contrast are prone to for feature computation. HOG is applied with trilinear noise, keypoints with low contrast are discarded using a interpolation to gain performance improvement. This paper examines the effect of interpolation on the performance of threshold. Then ...

... and power quality disturbances were analyzed. The signals were obtained by an experiment, so [12-21]. Probably, our first thought regarding above the occurrence of noise makes them much more complex to mentioned may be connected with application of Discrete analyze than the simulated ones. Their harmonic decomposition was performed by digital signal processing ...
216. Adaptive Quality Control Scheme Based on VBR Characteristics to Improve QoE of UHD Streaming Service
Year: 2019, Volume: 19, Number: 1
... (with variable bandwidth) frequently changes and degree of the changes is large, the Figure 1. Structure of HTTP adaptive streaming user feels that the video has noise and artifacts. To improve the QoE, the high-quality video should be played for a long In this paper, we propose an adaptive quality control time. ...

... and the state vector variables output values obtained as a result of an open-loop operation. of the system, respectively, and ek   l is the white noise In addition, the fact that the control algorithm works by looking at past input and output values during a specified disturbance. The system matrices A   ...

... appropriate or models have been examined comparatively. not for the problem. If the data is completely random, the model is approved by assuming that it has white noise [2]. 1) CNN Metrics such as AIC, MAE or RMSE can be used to evaluate the performance of models. Future predictions with CNN ...

... back into the original file. Encoding and decoding metrics: the root-mean-square error (RMSE), peak signal-to- processes are used in many applications, such as noise ratio (PSNR), compression ratio (CR), and similarity networking, data communication, and storage, to facilitate structure index metric (SSIM) ...
