The original stage of categorizing acoustic stimuli in the L2 signal often involves assimilation from L1 categories. Whether L1 sounds will assimilate to L2 ones can be assimilated to the L2 category is decided by difference of category distance. This study, with evidence from Cantonese learners' perception of the English tr-signal, proposes that a careful mining process to find out the intended assimilating L1 category is necessary. The chosen L1 category should be tested on perceptual similarity to the L2 category in fine-grained phonetic environments, rather than just possible L1 phonological mappings from observed production errors. Two experiments with different L1 assimilating candidates are done using the AX identification and ABX discrimination paradigms. Target trVC syllables are both aligned with twVC, a representative of phonological closeness through contrastive analysis, and with chVC, a representative of perceptually similar candidate which is less mentioned in literature. Results from both identification and discrimination show that accuracy rate for twVC is almost ceiling whereas that of trVC is significantly lower. Results suggest that perceptual distance is better represented by perceptual similarity and such screening process should be applied as a pre-examination procedure instead of choosing L1 assimilator based on phonological similarity.","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":" 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120830624","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}

The increasing of elder population is the main driven factor in implementing the medical intelligent services. Application of intelligent medical care system in the disaster environment is also not even less important. In such a vital application system as well as other large bandwidth requirement system, such as a cardiogram and heartbeat monitoring, the communication needs not only the reliability but also the realtime action. Considering the physical layer of IEEE 802.15.6 standard, Ultra Wideband offers an advantage in term of bandwidth availability. In this paper we propose the preliminary investigation of the application of error control code to MAC layer data. Of its both random and burst error correction capability, Reed-Solomon codes have been considered. In our investigation, several MIT-BIH Arrhythmia databases are chosen as input data. The coding scheme is applied to the 250 byte payload data. RS(250, k) which is the shorten version of RS(255, k) defined in GF(256) with variable code rate are investigated. AWGN channel and fading channels are employed to examine code's performance.","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":"25 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":"114941049","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}

Aiming at the poor performance of short term prediction of navigation satellite atomic clock errors, a method based on the least square support vector machine (LS-SVM) optimized by improved artificial fish swarm algorithm (IAFSA) is proposed to obtain accurate satellite clock errors. The dynamic parameter adjustment function is introduced to improve performance of artificial fish swarm algorithm. Then it was used to choose the penalty parameter and kernel bandwidth parameter of LS-SVM, which could avoid the man-made blindness during parameters selection of LS-SVM and enhance the efficiency of clock errors prediction. The clock data of four typical GPS satellites are chosen and make comparison and analysis with other three models. The results show that the prediction precision of the proposed method has better prediction performance than the traditional methods, which can afford high precise satellite clock errors prediction for real-time GPS precise point positioning system.","PeriodicalId":124509,"journal":{"name":"2013 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2013)","volume":"1 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":"130640002","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}
