Spectrally Efficient 1Tb/s Transceivers
Optical Fiber Communication Conference, 2015Based on recent Terabit-class transmission experiment, we discuss the design of 1Tb/s transceivers for long-haul optical systems involving complex tradeoffs between constellation complexity, opto-electronics bandwidth limitations, ROADM cascade, advanced FEC…

Spectral efficiency of multiple access techniques
Proceedings of IEEE Vehicular Technology Conference (VTC), 2002The terms modulation and multiple access are used to define two entirely different matters and hence the efficiency they contribute is separable. In theory, all multiple access techniques potentially have 100% relative spectral efficiency provided that the channels are orthogonal.

Spectral Efficiency Considerations
1997At the end of the day, whatever cellular radio system is considered, the following two factors will have to be taken into account: (i) The number of subscribers that can be connected to the system in an acceptable way for the radio spectrum allocated within a state or country desiring a cellular telephone service and (ii) the

Spectral efficiency analysis for LTE networks
2014 IEEE Fourth International Conference on Consumer Electronics Berlin (ICCE-Berlin), 2014This paper analyzes the uplink spectrum efficiency of an LTE network, taking intercell co-channel interference into account. This study is based on signal-to-interference-plus-noise ratio analysis and appropriate channel models including path loss and shadow fading.

On the spectral efficiency of wideband CDMA systems
IEEE Journal on Selected Areas in Communications, 2001The reverse-link spectral efficiency is evaluated for a direct-sequence (DS) code division multiple access (CDMA) cellular communication system that employs rapid closed-loop power control and coding with interleaving on channels that exhibit doubly selective Rician fading. The focus of the paper is the effect of the chip rate of the DS spread-spectrum
