To support multicast in a cost-effective way, the multicast of OTN should be realized in electronic domain based on ODU-level rather than optical domain in our point of view. In order to implement multicast routing in OTN, a new minimum cost tree heuristic algorithm is brought forward by us, which takes account of path sharing and load balancing. The simulation results show that the proposed multicast routing algorithm can achieve the preferable performance.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131488698","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}

We assume that multiple relay nodes in the network can cooperate their transmissions of information to gain energy savings in a distributed network MIMO system. We formulate the problem as maximizing the lifetime of the network in terms of maximizing the overall number of packets transmitted by the source to the destination, given a limited energy supply at the source node and each relay node along the transmission path. Unlike the existing method where all relay nodes cooperatively transmit to the receiving node, we construct a selection method to choose a subset of all relays to participate in the cooperative transmission. The chosen subset is the one that maximizes the lifetime of the network and we call the selection method a residual energy-aware cooperative transmission (REACT) algorithm. Our simulation results show that the proposed REACT algorithm demonstrate much improved lifetime compared to the existing method.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134371585","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}

Experimental proofs are presented. In addition, we report a novel self-clocking method based on in-band clock pilot insertion at the transmission data signal. The method provides clock recovery without an ultrafast phase comparator and a phase-locked loop in the receiver. Fast synchronization, low timing jitter and a highly stable recovered clock is demonstrated from 160 Gb/s OTDM data signal after 51-km fiber transmission.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117159411","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 bits allocation in OFDM subchannels is modeled as a binary sequences search problem, which is NP-Hard. First, the bits with the least cost in each subchannel are formulated as a possible solution with a predefined probability. Then a genetic-like algorithm is used to search the current local optima, which have the most allocated bits. The algorithm terminates until the total power is consumed or the mutual interference is over-the-threshold. Simulation results show that the performance of FGA is close to the optimal solution obtained by commercial software.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128215628","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}

Recently, the constellation extended scheme (CES) is an active technique for reducing PAPR of OFDM signals. However, this approach needs high computational load and more inverse Fast Fourier transform (IFFT) operations for finding the transmitted signal with minimum PAPR out. Therefore, this paper proposes a modified CES with lower computational load and IFFT operations than the CES in a 16-QAM OFDM system. Our proposed method, which combines the CES with the partial transmit sequences (PTS) technique, is also called CES-PTS. When compared to PTS techniques, our proposed method has no need to transmit side information in the transmitter.","PeriodicalId":427398,"journal":{"name":"The 19th Annual Wireless and Optical Communications Conference (WOCC 2010)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128140573","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}
