And the two issues of related SDH technology have become increasingly prominent in its transmission bandwidth and network expansion. In order to meet the demands of the future clean energy access, the energy strategy development, and the big data & cloud computing interconnection, the domestic power enterprises have implemented the construction of OTN network, which is characterized by high-speech accessing, flexible scheduling and secure managing. Based on the practices of power OTN projects, this paper proposed a section-coding wavelength-channel planning method, which is of the features in both practicing simply and calculating accurately. Firstly, the paper described the OTN planning methods in the view of its network advantages, which included services’ requirement statistics, section-coding steps, wavelength-channel planning principle and its configuration. Then, according to the actual services’ demand, the proposed method implemented OTN wavelength-channel planning by section-coding operation to achieve the accurate on-demand wavelength-channels allocation, which may ensure both services’ Quality of Service and the effectiveness of the related investment in ONT planning period.","PeriodicalId":66606,"journal":{"name":"无线通信","volume":"260 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2018-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66090708","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}

Due to the uncertainty of the speech in the statistical model of noisy speech, the unified processing of speech signals will inevitably result in the loss of speech components, which will affect the performance of speech enhancement. Therefore, this paper mainly studies and estimates the frequency of each signal. The speech probability is then combined with the gain function of the squared spectrum least mean square error algorithm to derive a new gain function. Finally, we can see through the experimental simulation, the algorithm proposed in this paper can significantly improve the voice quality and improve the intelligibility of the voice.","PeriodicalId":66606,"journal":{"name":"无线通信","volume":"08 1","pages":"141-147"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66091140","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}
