A novel method for encoding and decoding based on enhanced parity-check-concatenated polar codes by Yan WANG, Shunlan LIU, Zhenzhen XI, Jianrong BAO

“…A novel method for encoding and decoding based on enhanced parity-check-concatenated polar codes was proposed. The enhanced check bit was set up after the parity-check (PC) bit to check the information bits with low channel reliability again, which could help path metric value prune the decoding path and improve the reliability of decoding path selection. …”

Design of concatenated Hash-Polar code based on segmented CRC code by Zhengjie LI, Shunlan LIU, Xu ZHANG

“…As a linear block code, the polarization code has a lower coding complexity and a definite structure, but when it has a short or medium code length, the performance will be reduced.A design method of concatenated HashPolar codes based on segmented cyclic redundancy check (CRC) codes was proposed, which was based on the original Hash-Polar code and used CRC segmented check for double check.The segmented CRC code could assist the path measurement in the decoding process, that was, modify the decoding path, so as to improve the reliability of path selection and the performance.In addition, the segmented check was to add the check code dispersedly to the input information sequence.If the CRC failed during decoding, the decoding path could be terminated in advance to save unnecessary decoding calculations.Finally, at the end of the decoding, Hash check code verified the modified L paths and selected the best decoding path.The simulation results show that the design method proposed has better bit-error-rate performance than CRC-assisted Hash-Polar (Hash-CRC-Polar).In the Gaussian channel, when the code length is 128 bit, the code rate is 1/2, and the bit error rate is 10^-3, the Hash-Polar code based on the segmented CRC code proposed achieves a gain of about 0.25 dB over Hash-CRC-Polar.…”

Research on range matching for wire-speed hardware NIDS by CHEN Shu-hui, SUN Zhi-gang, SU Jin-shu

“…To solve the rule matching problem of hardware NIDS,a range matching algorithm LRC-RM was proposed,with more efficient memory utilization.The approach mapped the port range into a compressed bit vector and organized the bit vectors as an extended balanced binary tree.Experiments were employed to show that NIDS using this approach can perform wire-speed range matching for OC-192 links,while saving 99% memory resource comparing to the existing methods.The algorithm is easy to be implemented within a chip without additional RAM.…”

Performance analysis of uplink CDMA cellular systems based on the large system method by YU Kai1, FAN Ping-zhi2, HAO Li2

“…The performance of uplink of CDMA cellular systems with large and small scale fading was investigated based on the large system analysis.The intra-cell multiple access interference was firstly analyzed as well as the inter-cell in-terference.Then the signal to interference and noise ratio was deduced,the result of which was only dependent on the cell load,user power and channel coefficient.Finally,the bit error rate,throughput and spectrum efficiency were analyzed,which were confirmed by simulations.The simulation results show that as the cell load increases,the bit error rate in-creases and the throughput decreases.However,the spectrum efficiency increases monotonously.…”

AAC compression detection based on scaling factor transition probability by Qijuan HUANG, Rangding WANG, Diqun YAN

“…Audio compression history detection is an important part of audio forensics,which is important to detect whether audio has been tampered or forged.An algorithm of AAC audio compression history detection was presented by using the transition probability differences of scale factors as the discriminative feature.Experimental results demonstrate that the proposed method can distinguish the single,double and triple compressed AAC audios effectively,and from the low-bite-rate to high-bit-rate,the average classification accuracy achieves 99.75%,the same-bit-rate detection accuracy achieves 97.28%.In addition,the results of comparison experiments show that the proposed algorithm outperforms the state-of-the-art algorithm.…”
