OFDM Synchronization Errors and Effects of Phase Noise on WLAN Transceivers
This work aims at frequency synchronization in OFDM IEEE 802.11g Transceivers. The degradation of performance results from the detrimental effects introduced by frequency offset and phase noise. First, we present a robust method to detect and synchronize the OFDM signal with severe noise and interference corruption based on calculating the accumulated phase difference for each subcarrier. Then,...
متن کاملAnalytic Study of Synchronization Errors in Ofdm Systems Applied on Wlan Transceiver
In this paper, a new energetic approach was developed to study the impact of synchronization errors on OFDM transmission systems. Indeed, this approach can be applied in wireless communication systems such as HiperLAN and WLAN Transceivers. Firstly, the studies were conducted on the impact of timing errors on system performance and we have shown that stress recovery sampling frequency were part...
متن کاملthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
15 صفحه اولAnalysis of Efficient Time Synchronization Algorithms in OFDM WLAN
OFDM receiver starts its work with detecting the received signals from the transmitter, thus to detect the received signal synchronization algorithm is worked out especially time synchronization algorithm. This paper deals with the design of Coarse time synchronization module for OFDM-based WLAN. The circuit is particularized for IEEE 802. 11a/g standards. The algorithms simulated are selected ...
متن کاملAnalysis of the Influence of Phase Noise in MIMO OFDM based WLAN systems
The influence of phase noise (PN) on the performance of a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) based communication system is analyzed. A PN power weighting function is derived which indicates the influence of the different subcarriers and the shape of the PN spectrum. For compensation of the common phase error (CPE), the maximum likelihood esti...
