A spectral-phase encoded OCDMA system is demonstrated in a back-to-back optic fiber link. Code-division discrimination is successfully achieved using a self-homodyne technique at 500Mb/s channel data rate with a BER of 8.9x10-5 for two simultaneous users. OCIS codes: (060.1660) Coherent communications; (140.4050) Mode-locked lasers; (060.2330) Fiber optics communications.
Discrete-multitone modulation for short distance 100 Gbit/s optical links
- Pilori D.
The commercially available 100 Gbit/s optical channel employs coherent modulation and demodulation allowing transmission over long distances, up to thousands of kilometers, but for short distances the cost of a coherent receiver can be overkill. In literature there are several techniques, based on advanced different digital modulation schemes, that reduce ...
Enhanced Control Signal and Data Detection for 5G Multicarrier Low-Power Communications
- Chen Y.
- Doll M.
As being a complementary technique for Machine Type Communications (MTC) in future 5th Generation (5G) wireless communications, the control mechanism and control signaling should preferably be able to operate at possibly low Signal-to-Noise Ratio (SNR) without interfering the existing cellular network. In this paper, we propose an enhanced mechanism for ...

Due to the increasing need of health monitoring at home or in senior center, we study the optimal relay node placement problem for wireless sensor networks with data collection and localization requirements. The problem can be modeled as finding a minimum connected k-dominating set. We consider realistic indoor wireless environment ...
A Distributed eICIC Algorithm for Joint Inter-cell Interference Management and User Attachment in LTE-A HetNets
- Albert Sung

- Chen C.
- Liu Y.
In Long Term Evolution-Advanced (LTE-A) heterogeneous networks (HetNets), it is crucial to address the intercell interference and the user attachment problems in order to obtain good network performance. Moreover, the two problems are coupled and therefore must be tackled together. Based on potential game formulation, we jointly optimize almost blank ...

A novel perturbative-based algorithm to jointly compensate intra and inter-channel nonlinearities of the subcarriers of a super-channel is introduced for the first time, and demonstrated in a transmission experiment of a quad-carrier 30.75 GBd PDM-16QAM over transoceanic distances.

Chapter 9 (METIS Book) Multi-node Coordination
- Aziz D.
- Baracca P.
- Fantini Roberto
- Thiele L.
- Zirwas W.
Performance in a wireless network strongly depends on user position in the cell, with users in the cell border typically experiencing much lower throughputs than those nearer to the transmitting base station. This is mainly due to the presence of inter cell interference, generated by concurrent transmissions in other cells. ...
