In our method, we perform the clustering of the base-band symbols to recognize the constellation and evaluate the result by some validation method. For clustering, K-Means, one of the simplest and fastest clustering methods, and the Fuzzy Hyper Volume (FHV), a well-known, simple and fast index for validating fuzzy C-Means clustering method, are employed. The presented approach is fully unsuper-vised and performs its task despite the slowly-varying flat Rayleigh fading channel and without the knowledge of the parameters such as SNR, carrier phase and timing offset. Using this fast and accurate pair of method-index and introducing a novel idea for refining K-Means initial values that considerably increases accuracy and decreases the number of iterations required for K-Means clustering, guarantees high performance and low computational complexity of the aforementioned algorithm. It is shown via simulations that the algorithm performs correct classification when the SNR is over 10dB for most practical linear modulation schemes under the presence of AWGN.","PeriodicalId":343415,"journal":{"name":"International Workshop on Systems, Signal Processing and their Applications, WOSSPA","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129322975","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}

It is a life-saving procedure used in the treatment of medically refractory intracranial hypertension, most commonly in the setting of trauma or cerebral infarction. Essentially, any increase in the volume of the contents of the skull is first treated to be contained. If such treatments fail, then the related part of the skull is removed through surgery and the increase of volume is allowed to happen until the pathology subsides and the brain returns to its normal relaxed state. After which the defect is repaired by a procedure called Cranioplasty in which case the left-out bone is placed back and joined onto the skull. This procedure is extremely risky but is becoming very popular due to clinical successes. The determination of risk of complications at the stage of bone-replacement can be a very useful information for the doctor as well as the patient since it can determine the post-surgical treatment, care, and patient-management procedures. In this paper, we have proposed a very systematic algorithmic approach to determine this using Fuzzy Inference System. The system inputs many qualitative as well as numerical inputs and determines the risk as one of the clsses of complications; Severe, Minor, Least/None.","PeriodicalId":343415,"journal":{"name":"International Workshop on Systems, Signal Processing and their Applications, WOSSPA","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130009822","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}
