Capacity of the distributed storage system (DSS) is often discussed in the context of tradeoff between storage overhead and repair bandwidth. This paper considers capacityachieving coding for the clustered form of distributed storage that reflects practical storage networks. The suggested coding scheme is shown to exactly regenerate the arbitrary failed node with minimum required bandwidth, i.e...

Severe frequency-selective fading, encountered in a broadband wireless mobile communication, significantly degrades the bit error rate (BER) performance of direct sequence spread spectrum (DSSS) signal transmission with rake combining. In this paper, frequency-domain pre-equalization transmission, called pre-FDE transmission, is presented for orthogonal multicode DSSS signal transmission. It is...

Adaptive prediction iterative channel estimation is presented for combined antenna diversity and coherent rake reception of direct sequence spread spectrum (DSSS) signals. Its first stage uses pilot-aided adaptive prediction channel estimation, while the succeeding iteration stages use decision feedback and moving average filtering for channel re-estimation. The bit error rate (BER) performance...

People are increasingly employing artificial intelligence as the basis for decision-support systems (DSSs) to assist them in making well-informed decisions. Adoption of DSS is challenging when such lack support, or evidence, justifying their recommendations. DSSs widely applied medical domain, due complexity domain and sheer volume data that render manual processing difficult. This article prop...

The linear frequency modulation (LFM) interference is one of the typical broadband interferences in direct sequence spread spectrum (DSSS) communication system. In this article, a novel parameter estimation method LFM proposed for DSSS system alpha-stable noise. To accurately estimate parameters, noise should be eliminated first. Thus, we formulate new generalized extended chirplet transform to...

For many years, manufacturers have focused on improving their productivity. Production scheduling operations are critical for this objective. However, in modern manufacturing systems, the original schedule must be regularly updated as it takes places a dynamic and uncertain environment. The environment is therefore very stressful managers charge of production process because they to cope with d...

Radio Frequency (RF) interference is inherent in all wireless systems and is one of the most significant design parameters of cellular and other mobile systems. In this paper, it is shown that how a non-linear adaptive Volterra filter (Polynomial filter where input and output signals are related through Volterra series) helps track the statistics of the input data and dynamics of a direct seque...

 In this paper, the coverage region of communication quality degradation would be indicated. The index of PER (UDP packet frame error rate) is employed to evaluate the communication quality and verify the prediction results. Moreover, by measuring the interference in terms of PER, the dependence of the microwave oven interference on the whole communication channels in the IEEE 802.11 DSSS wire...
