Performance Analysis of MIMO-OFDMA Wireless System Using OSTBC Over Rayleigh Fading Channel

Ashwaq Q. Hameed Al Faisal

Volume 13, Issue 1 , April 2013, Page 1-8

  Abstract –This paper presents performance analysis of Multiple-Input Multiple-Output - Orthogonal Frequency Division Multiplexing Access (MIMO-OFDMA) wireless system using orthogonal space time block code (OSTBC) over Rayleigh fading channel. OSTBC is an efficient code system that achieves the maximum ...  Read More ...

Design and Implementation of Adaptive Wavelet Network PID Controller for AQM in the TCP Network

Dr. Farooq Al- doraiee; Salih Al-Qaraawi; Hassan J. Hassan

Volume 13, Issue 1 , April 2013, Page 9-17

  Abstract – Internet represents a shared resource wherein users contend for the finite network bandwidth. Contention among independent user demands can result in congestion, which, in turn, leads to long queuing delays, packet losses or both. Congestion control regulates the rate at which traffic ...  Read More ...
