We introduce the mode dimension to increase the number of labels that can be generated and processed by a single multiport E/D, and we analyze configurations with reduced intra-mode crosstalk. We show that the label error rate is significantly influenced by inter-mode crosstalk, being TE10 labels more susceptible to crosstalk from adjacent ports, than TE00 labels.","PeriodicalId":54101,"journal":{"name":"IEICE Communications Express","volume":"13 11","pages":"440-443"},"PeriodicalIF":0.3,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10675417","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, end-to-end (E2E) communication quality including network quality and edge computing processing time is very important for IoT remote control. However, current measurement tools cannot measure the E2E quality directly when edge processing is involved. Therefore, the network quality and the processing time of edge applications need to be separately measured. Measuring the processing time of these applications requires not only modifications for each application in conventional methods but also complicated configuration work. Therefore, we propose a method to measure the processing time of edge applications by detecting packets embedded with unique identifiers, without requiring any configurations to applications. The implementation and evaluation results show that our method can accurately measure the processing time required on edge application.","PeriodicalId":54101,"journal":{"name":"IEICE Communications Express","volume":"13 11","pages":"426-430"},"PeriodicalIF":0.3,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10675421","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Time and frequency sampling of scalogram are not uniform to eliminate redundancy. One method achieves fine time sampling with fewer operations, but the frequency direction sampling is not uniform or fine, and sidelobes are high. To address these problems, this study proposes a simple wavelet transform with fine time and frequency sampling. The proposed method consists of phase multiplication and signal addition. Frequency transform of any time window width is possible by changing the additive width of the signal. Furthermore, by adding the results, wavelet transform using a triangular window that lowers sidelobes is realized using a small number of complex multiplication operations. When the proposed method is applied to a chirp waveform, the frequency transition of the signal could be finely confirmed.","PeriodicalId":54101,"journal":{"name":"IEICE Communications Express","volume":"13 10","pages":"397-400"},"PeriodicalIF":0.3,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10633230","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142377145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In cellular communication systems, the compression ratio must adapt to channel fluctuations, requiring multiple training models at the base station.

Passive Optical Networks (PON) traditionally operate on the principle of ensuring service provision to the farthest user. Consequently, performance tends to be excessive for short to medium distances, leading to surplus power consumption. In this study, we address the issue of reducing power consumption in access networks by tackling surplus power. Our approach involves utilizing three different types of Reed-Solomon (RS) decoders to apply appropriate forward error correction (FEC) redundancy based on transmission distance, aiming to lower power consumption of RS decoders in optical network units (ONUs). Subsequently, we evaluated the power saving of FEC decoding in a 10G-class PON and report over 48% average power saving compared to the conventional homogeneous FEC-based network.","PeriodicalId":54101,"journal":{"name":"IEICE Communications Express","volume":"13 10","pages":"401-404"},"PeriodicalIF":0.3,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10633221","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142377147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
