An aggregate data-rate of 600 Mb/s is measured over 6 meters link distance with a bit-error-rate (BER) below 10−3 with the 4-channels simultaneously modulated. While the majority of published VLC works to date use components-off-the-shelf (COTS) PIN or Avalanche PDs that require both non-standard and/or higher cost fabrication processes as well as high reverse bias potential, the presented receiver in this paper employs a 2×2 on-chip Nwell/Psub photodiodes (PD) array fabricated in a low cost CMOS-compatible process. To extract high data rate performance out of the proposed CMOS low speed PD array, a 2nd-order LCR equalization is used to compensate for the stringent bandwidth limitation of the PD, measured around 20 MHz and push the speed up to 150 Mbps/channel. With a red light-emitting-diode (LED) array at 650 nm, the 4-channels MIMO setup DC power consumption is 1.38 W, which represents to our knowledge an energy-per-bit record performance for OOK VLC systems of 2.3 nJ/bit.","PeriodicalId":6471,"journal":{"name":"2017 26th Wireless and Optical Communication Conference (WOCC)","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2017-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88123261","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}

In particular, virtual networks from distinct tenants can be provisioned on the same physical network infrastructure to share the computing and networking resources through a process called virtual network mapping, which can lead to an efficient utilization of the underlying physical resources while guaranteeing the service isolation and performance efficiency. In the process of provisioning virtual networks, it is critically important to ensure that the virtual network services are resilient and they have the capability to continue functioning well in case of various failures such as fiber cuts, natural disasters and malicious attacks. In this paper, we study the problem of resilient virtual network mapping against large-scale regional failures, which are more challenging than existing network survivability designs in terms of single node/link failures or shared risk link group failures. We propose a novel region-disjoint mapping (RDM) algorithm which can map the primary and backup virtual networks into nonoverlapping geographical areas to survive large-scale regional failures. More specifically, the RDM algorithm adopts (1) the backtracking techniques to ensure the disjointness of the primary and backup virtual networks, and (2) the Suurballe's algorithm to jointly optimize the mapping of primary and backup virtual networks in one-step. Simulation results show that the proposed RDM algorithm achieves much lower physical network resource consumption and blocking probability.","PeriodicalId":6471,"journal":{"name":"2017 26th Wireless and Optical Communication Conference (WOCC)","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2017-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89986011","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}

An SH system eliminates the need of a local oscillator (LO) and a carrier phase recovery (CPR) module at the receiver. Due to the inherent line-width tolerance of SH systems, an expensive laser is not required at the transmitter. In digital processing based receivers, analog-to-digital converters (ADC) are the dominant source of power and cost; signal processing in the analog domain can get rid of the usage of ADCs. Combination of these two approaches can lead to a huge power and cost saving. An SH-QPSK system with a polarization multiplexed carrier is experimentally demonstrated with a 28km standard single mode fiber (SSMF) channel and off-line signal processing at the receiver side. The system does not use any optical amplification and dispersion compensating fiber. A novel analog domain constant modulus algorithm-decision feedback equalizer (CMA-DFE) is proposed which is a cascade combination of two different types of equalizers. This proposed scheme gives improvement in the performance over an optimum CMA equalizer, because of the difference of minimum mean square errors (MMSE) of two different cost functions.","PeriodicalId":6471,"journal":{"name":"2017 26th Wireless and Optical Communication Conference (WOCC)","volume":"26 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2017-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81858632","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}
