high spectral Efficiency optical direct detection using the stokes vector receiver
European Conference on Optical Communication, 2015Co-Authors: Di Che, William ShiehAbstract:We review the optical direct detection subsystems based on the Stokes vector receiver (SV-R), which is fit for a variety of modulation formats in Stokes space. SV-R accommodates 2-dimension (2-D) or 3-D detection, greatly increasing the Spectrum Efficiency.

stokes vector direct detection for short reach optical communication
Optics Letters, 2014Co-Authors: Di Che, Xi Chen, Yifei Wang, William ShiehAbstract:We propose the Stokes vector direct detection (SV-DD) scheme which simultaneously achieves receiver phase diversity and the cancellation of photodetection nonlinearity. An 80 Gb/s single-polarization modulated SV-DD signal is successfully received after 160 km SSMF transmission with 11.64 bit/s/Hz electrical Spectrum Efficiency.

superframe level time hopping system with variable contention access period for wireless body area communications
Personal Indoor and Mobile Radio Communications, 2011Co-Authors: Jian Zhang, Leif Hanlen, Andrew Y. Wang, Xiaojing HuangAbstract:Coexistence of multiple wireless body area networks (WBAN) is a very challenging problem because piconets move frequently and each piconet can have hundreds of sensors. The IEEE 802.15.6 task group is developing a standard based on superframe-level frequency-hopping scheme, which is a good solution to the piconet coexistence problem without requiring coordination between piconets. However, its Spectrum Efficiency is very low when only a single piconet is operating. In this paper we propose a superframe-level time-hopping scheme with variable contention access period. Compared to the frequency-hopping scheme, the proposed scheme has similar interference mitigation capability, but can achieve significant improvement in energy consumption, latency and Spectrum Efficiency.

performance analysis of soft frequency reuse for inter cell interference coordination in lte networks
International Symposium on Communications and Information Technologies, 2010Co-Authors: Eryk Dutkiewicz, Xiaojing Huang, Markus Dominik Mueck, Gengfa FangAbstract:Due to the requirement of high Spectrum Efficiency, the frequency reuse of one is targeted for next generation OFDMA-based cellular networks. Such a frequency planning strategy can lead to unacceptable inter-cell interference levels experienced especially by users located at the cell edge area. Soft frequency reuse (SFR) is considered as an effective frequency reuse scheme for inter-cell interference coordination as well as maintaining Spectrum Efficiency. In this paper, we investigate the performance of SFR for LTE downlink transmission by considering issues of various traffic loads and different power ratio configurations. In addition to the cell-edge user performance, the overall cell performance and the cell-center user performance are both evaluated in terms of throughput estimation. Using simulation studies, the advantages and limitations of SFR are comprehensively examined and compared against the classical frequency reuse of one scheme.
