Passive optical network for microcellular CDMA personal communication service

H. Kim, J.M. Cheong, Chang-Hee Lee, Y.C. Chung
1998 IEEE Photonics Technology Letters  
The proposed network is based on a passive double-star architecture. The relaxed dynamic range requirements of CDMA signals allowed the use of double-star architecture.  ...  We propose and demonstrate a fiber-optic network for microcellular code-division multiple access (CDMA) personal communication service.  ...  In this letter, we propose and demonstrate a fiber-optic network based on a passive double star for CDMA PCS.  ...

Passive optical network for CDMA-based microcellular communication systems

H. Kim, Y.C. Chung
2001 Journal of Lightwave Technology  
Motivated by this relaxed requirement, we have recently proposed a passive optical network for CDMA-based microcellular communication systems.  ...  In this paper, we reviewed the basic design rules and demonstrated various networks using double-star and ring architectures.  ...  ACKNOWLEDGMENT The authors would like to thank J. M. Cheong of SK Telecom for measuring the dynamic range of upstream CDMA signals at commercial PCS base stations.  ...

Antenna interconnection strategies for personal communication systems

H. Yanikomeroglu, E.S. Sousa
1997 IEEE Journal on Selected Areas in Communications  
Microcellular and distributed antenna systems are two promising candidates for implementing personal communication systems.  ...  The significant reduction in conduit and cable lengths that the Steiner minimal tree (SMT) architecture provides over the star type, especially in large networks, is demonstrated.  ...  This network may correspond to a fiber optic microcellular system utilizing SCM, or to an SDA system with one antenna element per sector.  ...

Signal processing for optical fiber based wireless access

Xavier N. Fernando, John C. Armitage
2017 Opto-Canada: SPIE Regional Meeting on Optoelectronics, Photonics, and Imaging  
In reality, the individual fibers may be interconnected as a bus network, or as a star network or an hybrid of these two schemes.  ...  In the resistive matching technique, a passive matching network consisting of only resistive elements is used.  ...  When the nonlinearity has no memory, these distortions produces a 'warped' con- A.2 Inband Nonlinear System  ...

Bandwidth-efficient wireless multimedia communications

L. Hanzo
1998 Proceedings of the IEEE  
order to meet backward compatibility requirements with existing systems and to achieve best compromise among a range of conflicting system requirements in terms of communications quality, bandwidth requirements  ...  Following a brief introduction to speech, video, and graphical source coding as well as the cellular concept, a rudimentary overview of flexible, reconfigurable, mobile radio schemes is provided.  ...  The multimedia PS's communicate with the so-called BS's in their vicinity, which are interconnected either directly using optical fiber or in more complex systems via MSC's.  ...
