Power Spectral Density Analysis of WLAN based OFDM System
OFDM is a technique used in modern broadband wireless communications systems. OFDM has been adopted for wireless standards such as IEEE 802.11a. In this paper, different Power Spectral Density (PSD) curves of OFDM signal based on WLAN with various pulse shapes are presented. OFDM waveform is analyzed in frequency domain response for different modulation techniques such as BPSK, QPSK, 16-QAM, 64...
متن کاملLow Power Efficient MIMO-OFDM Design for 802.11n WLAN System
In modern world of communication systems, various new methods have developed to replace the previous conventional techniques that provide data communication with high speed. As wireless communication guidelines were developed it became necessary to develop new techniques like Orthogonal Frequency Division Multiplexing (OFDM) for data security and reliability while data transmission. Idea behind...
متن کاملOFDM Based WLAN Systems
This report is intended to provide an overview of the present state of WLANs with respect to physical layer issues and identify some key research issues for future generations of WLANs. The current standards (IEEE 802.11a in USA, HiperLAN/2 in Europe and MMAC in Japan) are all based on OFDM in their PHY layer. Thus, detailed attention on basics of OFDM related WLAN systems are given in the repo...

15 صفحه اولImplementation & Performance Analysis of Cordic in Ofdm Based Wlan System Using Vhdl
This paper is focused on the implementation of CO-ordinate Rotation Digital Ccomputer (CORDIC) algorithm in wireless Local Area Network (WLAN) receiver. The primary task is to create a VHDL description for CORDIC vector rotation algorithm. The basic work has been carried out in MATLAB. The VHDL implementation of the CORDIC algorithm is based on the results obtained from the MATLAB’s simulation ...
