Significant network capacity gain can be achieved not only through aggressive reuse of spectrum across the multiple tiers in the network, but also by integrating WiFi in the mobile network through additional spectrum in un-licensed bands. Different criteria should be investigated in order to allow both the WiFi APs and the end user to operate on the best suitable channel, where the basic one of those criteria is the \"load\" of the operating channels. We propose in this paper an accurate algorithm for the estimation of WiFi 802.11n physical channels load through 3 channels observations only. Once the channel load is estimated using the proposed algorithm, the channel assignment based on the minimal load value is acquired, thus providing faster response of an AP channel selection and faster end user connection for better Quality of Experience (QoE).","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130572211","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 universal timedomain windowed OFDM (UTW-OFDM) have been proposed as a waveform that has the low OOBE characteristics and high compatibility with the conventional cyclic prefix OFDM (CP-OFDM)-based systems. To indicate the feasibility of the UTW-OFDM-based system in the 5G and beyond, the comprehensive evaluation of the UTW-OFDM-based LTE system is important, however, the evaluation of the UTW-OFDM-based LTE system complexity has been not reported. Furthermore, the communication quality of the UTW-OFDM-based LTE system was evaluated by using BER characteristics on the short delay multipath propagation channel in the previous studies. In this paper, to show the feasibility of the UTW-OFDM for the 5G and beyond, the complexity of the UTW-OFDM-based LTE downlink (DL) system is evaluated and compared with one of the LTE-DL system with the conventional CP-OFDM and the filtering-based waveform (UF-OFDM). The complexity of the conventional CP-OFDM-based system and the UTW-OFDM-based system is about 0.45 % of the complexity of the UF-OFDM-based system. Furthermore, the communication quality of the UTW-OFDM-based LTE-DL system is evaluated by using BLER on the 3GPP Extended Typical Urban (ETU) channel model with the 70 Hz Doppler shift. The UTW-OFDM-based LTE-DL system can improve the OOBE of the conventional CP-OFDM-based LTE-DL system by 45 dB with only 2.0 dB deterioration of EN0 to achieve BLER = 10−1 even if the 64QAM is applied with a half coding rate.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121345543","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 SSC-FDM arranges subcarriers non-orthogonally in the frequency domain and improves spectral efficiency by compressing the channel bandwidth compared to the conventional orthogonal frequency division multiplexing (OFDM). On the other hand, the inter-carrier inference (ICI) mainly caused by overlapped adjacent subcarriers deteriorates the communication quality. The SSC-FDM using soft canceller followed by minimum square error filter (SC-MMSE) turbo equalization has been reported to remove the ICI in the additive white Gaussian noise (AWGN) environment, while no meaningful result in the multipath fading environment has been reported at present. In addition, the SSC-FDM poses considerable difficulties in proper channel estimation and equalization in the frequency domain due to the non-orthogonal subcarrier arrangement. In this paper, we propose a receiver architecture in which time-domain equalization schemes are applied to the SSC-FDM using SC-MMSE turbo equalization, assuming the mobile communication system. In addition, the usefulness of the proposed scheme is discussed with regard to the block error rate (BLER) and throughput performance in the multipath fading environment by computer simulation.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133302711","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}
