Given the channel model and transmission constraints, the information theory enables to compute rate at which reliable communication is possible. Once this rate or in other words the channel capacity is calculated, it is the task of system engineer to devise coding schemes that approach this capacity. Though the Shannon theory appears to be computationally feasible, still it was not practically implementable. The invention of turbo codes was established as an approach of reaching close to Shannon limit. The performance of turbo code depends largely on the design of interleaver. The bit error rate and delay incurred in encoding and decoding are highly influenced by the interleaver. In this paper, sub-blocking based interleaver architecture is proposed which can be extended to any existing interleaver structure. The advantage of sub-blocking the input frames is that the complexity of the interleaver reduces and consequently the execution time will be reduced drastically. In addition, a simultaneous processing of interleaving and de-interleaving can be achieved. In this paper, the said architecture is verified for block and 3GPP interleavers with different combinations. It is shown that a reasonable BER is achieved in very less time compared to all existing interleavers.","PeriodicalId":443423,"journal":{"name":"2017 International Conference on Circuits, Controls, and Communications (CCUBE)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114143962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Audio steganography is a technique of hiding secret message inside an audio signal in an imperceptible manner. This paper discusses the implementation and analysis of an audio steganographic technique utilizing Direct Sequence Spread Spectrum (DSSS) scheme. The algorithm is enhanced to provide additional security by combining steganography with encryption. The secret message is first encrypted using a cryptographic algorithm, and then embedded in a cover audio using DSSS technique. The imperceptibility, security, capacity and accuracy of the proposed system have been evaluated using various performance metrics such as Signal to Noise Ratio, Peak signal to Noise Ratio, Bit Error Rate, Strength Factor, Chip Rate etc. After analyzing the experiment results, it is observed that the proposed implementation gives a more secure and robust steganographic system on the expense of compromising the embedding capacity. Such a system is ideally suited for covert communication in hostile environments, such as those related to military, defense and cyber intelligence, where short messages need to be communicated with high levels of security. The message embedding capacity could however be improved by increasing the capacity of the audio cover.","PeriodicalId":443423,"journal":{"name":"2017 International Conference on Circuits, Controls, and Communications (CCUBE)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117132410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
