Enhanced overloaded code division multiple access for network on chip by Behnam Vakili, Morteza Gholipour

“…On the other hand, one drawback is that the number of transmitters is limited to the number of encoding bits. In this study, the authors used the combination of Walsh codes and their inverses, as well as the simultaneous application of the time‐division multiple access (TDMA) method, to increase the transmission capacity of this protocol more than four times the standard mode. …”

Parameter selection of autocorrelation test for block ciphers by FAN Li-min1, FENG Deng-guo1, ZHOU Yong-bin1

“…Autocorrelation test was a statistical test to evaluate the correlation between one sequence and the corresponding non-cyclic left-shifted d bits sequence.It was impractical to adopt all the values of d since its range was often very wide.Three relations between parameters of randomness test were defined firstly.Then the relationships among the subclass D={1,2,m/4,m/2,3m/4,m,2m}of autocorrelation test for block cipher were studied by statistical experiments,where m was block length.The experiments show that the prefer choice of parameter d is m when doing autocorrelation test for block cipher.The method is also available for parameter selection of other randomness test for other types of cryptosystem.…”

Research on adaptive rate control algorithm for H.264 based on R-Q model by Xin-zi ZHENG, Bing-qing LUO, Zhi-xin SUN

“…The foundation theory of rate control theory in H.264 video coding standard was analyzed.The latest research work about rate control algorithm were summarized.On the basis of analysis.A novel frame-level rate control algorithm was proposed.Firstly,in order to reduce the inter-dependency between RDO (rate-distortion optimization) and rate control,a kind of two-stage rate control algorithm was presented.Secondly,to provide more accurate prediction of the frame complexity,instead of the MAD (mean absolute difference),bits information in the RDO-based mode decision process was employed to predict the frame complexity.Thirdly,a self-adaptive exponential R-Q model was proposed.The proposed rate control algorithm overcomes the disadvantages in the rate control precision and encoding performance of former algorithms.…”
