We experimentally demonstrate an underwater wireless optical communication (UWOC) with 1.4-Gbaud 16-QAM signal using Gaussian mode, orbital angular momentum (OAM) mode and Bessel mode at the wavelength of 532 nm. Underwater bubbles effect is also studied and the BER performance is measured.
In this paper we present a local channel correlation based zero-forcing (ZF) beamforming framework for the cell edge users. Without the instantaneous CSI (ICSI) assisting, we derive the exact expression of the averaged pairwise error probability (PEP) upper bounds at both of the receivers. According to the derived PEP bounds, an multi-objective optimization problem is formulated to get the elaborate...
A novel QPSK receiver based on a phase noise reduction pre-stage exploiting PSA in a HNLF and balanced detection is presented. Receiver sensitivity improvement over a conventional balanced receiver is demonstrated.
Service co-production and service co-creation have been in service context, and attract more interest recently. But the researches are lack of systematic organization, and even boundary between the two concept is not clear. This paper aims to distinguish service co-production and service co-creation. Moreover, deeper investigation on service co-production is provided. We established a model picture...
Cellular controlled Device-to-Device (D2D) system is a local service for future communication systems like LTE, LTE-A, etc. D2D communications can share the Uplink (UL) or Downlink (DL) resources with cellular communications to improve system throughput. Since reusing UL resource or DL resource has different merits in different scenarios, if D2D only reuses either UL or DL resource during the whole...
We demonstrate simultaneous demodulation of multiple 40 Gbit/s WDM NRZ-DPSK channels using a single silicon microring resonator with FSR of 100 GHz. Bit error measurements show very good performances for both through and drop demodulations for all channels.
