Both algorithms are based on the same main idea: the decreasing of the syndrome weight on each step of the decoding algorithm. The first decoding algorithm uses the properties of the constituent Hamming code. The best known lower-bound on the guaranteed corrected errors fraction for the H-LDPC codes under the first decoding algorithm was obtained in 2011. The second decoding algorithm considers H-LDPC as the irregular LDPC code and uses the well-known majority decoding algorithm. The lower-bound on the guaranteed corrected errors fraction for H-LDPC code under the second decoding algorithm is introduced for the first time in this paper. Numerical results for the lower-bound, obtained in this paper for H-LDPC code under the second decoding algorithm, significantly exceed the numerical results for the best known lower-bounds, obtained previously for H-LDPC code under the first decoding algorithm.","PeriodicalId":270689,"journal":{"name":"2014 XIV International Symposium on Problems of Redundancy in Information and Control Systems","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115822893","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}

While on the first iteration of the conventional turbo decoder a priori reliabilities are supposed to be zero in the new scheme it is proposed to estimate and set these values. Algorithm for generation of a list of a priori LLRs is described, where each list sequence is used as an input to independent turbo decoder. As a result list of decoded sequences is obtained from independent turbo decoding processes. Thus new turbo code list decoding algorithm is proposed and parallel turbo decoding technique is introduced. FER simulation results for 3GPP LTE turbo code show 0.4 dB gain for short information sequences and 0.15 dB gain for longer ones. As a criterion of choosing of correct sequence in the list CRC is used.","PeriodicalId":270689,"journal":{"name":"2014 XIV International Symposium on Problems of Redundancy in Information and Control Systems","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114976845","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}

This paper proposes novel iterative algorithm of IC in OFDM systems for the case when one of the interfering packets is known to the receiver. Comparing to well-known successive interference cancellation (SIC) methods, proposed algorithm works when there is no significant power imbalance in received signals and receiver could not decode the strongest one. The algorithm exploits the property, that duration of channel response in time domain is constrained while residual interference is widespread over the frequency and time.","PeriodicalId":270689,"journal":{"name":"2014 XIV International Symposium on Problems of Redundancy in Information and Control Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129285558","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}
