The iterative decoding approach based on the well known Extended-Min-Sum (EMS) algorithm, considered as the most efficient decoding algorithm to decode NB-LDPC codes, executes the decoding process iteratively. The main operations of this algorithm are the variable and check node updates which are performed at least eight times requiring a long decoding time to achieve good performance in terms of Frame Error Rate (FER). The proposed decoding near ML approach is based on ML search where the number of candidates is highly reduced using a technique privileging the most reliable and nearest codewords. Simulation results show that the proposed algorithm achieves, at a reduced list of 5 searched candidates in average at 3 dB, the performance offered by the EMS algorithm. We also show that by slightly increasing the list of candidates, the proposed algorithm outperforms the EMS algorithm.","PeriodicalId":361750,"journal":{"name":"2013 13th Mediterranean Microwave Symposium (MMS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127067334","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}

Two symmetrical quarter-circle shaped segments are cut both on the each of lower edges of the radiating patch and on the each of upper edges of the ground plane. These segments provide a wider bandwidth than the ordinary rectangular antenna especially in the middle frequencies. By means of removing U-shaped slot in the radiating patch the radiation characteristics of the 7-10 GHz frequency range are improved. Two half-circle shaped parasitic patches are connected via a hole to the ground plane. These patches are added on both sides of the 50-Ω microstrip-fed line to achieve good radiation performance for frequencies higher than 10 GHz. The proposed antenna is simulated by ANSYS's HFSS program using finite element method (FEM).

Using the proposed algorithm, the mean hop size hs is locally derived at each regular or position-unaware node, thereby avoiding its broadcast by anchors (i.e., a few nodes aware of their exact position) as usually required in current state-of-the-art solutions and, hence, resulting in less battery power depletion. The analytical expression of hs is derived for different node distributions. Furthermore, it is shown that it is possible to locally compute h̅s at each regular node with or even without prior knowledge of the node distribution. Simulations results show that the proposed scheme outperforms the most representative hop count based localization schemes in terms of accuracy.","PeriodicalId":361750,"journal":{"name":"2013 13th Mediterranean Microwave Symposium (MMS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127977233","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}
