Description: With the increasing demand of higher data rate for telecommunication, the IEEE802.11n standard was constituted in 2009. The most important character of the standard is MIMO-OFDM, which not only improves the throughput but also the spectrum efficiency and channel capacity. And in wireless communication, the role of MIMO detectors plays an important part to remove inter-symbol interference (ISI) caused by multipath fading channel. In this paper the BER performance of IEEE 802.11n for 3x2, 4x2 and 4x3 antennas are compared using MMSE and ZF detectors in Matlab Simulink. Platform: |

Description: This text is written for use in a second course in circuit analysis. It encompasses a spectrum of
subjects ranging from the most abstract to the most practical, and the material can be covered in
one semester or two quarters.The reader of this book should have the traditional undergraduate
knowledge of an introductory circuit analysis material such as Circuit Analysis I with
MATLAB®Computing and Simulink®/ SimPowerSystems®Modeling, ISBN 978-1-934404-17-1.
Another prerequisite would be a basic knowledge of differential equations, and in most cases,
engineering students at this level have taken all required mathematics courses. Appendix H serves
as a review of differential equations with emphasis on engineering related topics and it is
recommended for readers who may need a review of this subject. Platform: |
