Abstract
  Massive Multiple-Input Multiple-Output (MIMO) is an extension of the conventional MIMO in the wireless systems which improves both of the access density and the spectral efficiency by adding a massive number of antenna array at the base station (BS). Massive MIMO increases the spectral efficiency by ...  Read More ...

Spectral Efficiency Improvement of the Optical Communication Systems

Aqeel R. Farhan; Dr. Ali Y. Fattah

Volume 14, Issue 1 , April 2014, , Page 44-57

Abstract
  Abstract –In this paper, different amplitude and phase modulation formats are investigated and compared to find the optimum one among them for high spectral efficiency (SE) Wavelength Division Multiplexing (WDM) systems with an acceptable value of the Bit Error Rate (BER). Also, the effectiveness of ...  Read More ...
