Comparison of ACO-OFDM, DCO-OFDM and ADO-OFDM in IM/DD Systems
Journal of Lightwave Technology, 2013In this paper, three forms of orthogonal frequency division multiplexing (OFDM) designed for intensity modulated/direct detection (IM/DD) optical systems are compared. These are asymmetrically clipped optical OFDM (ACO-OFDM), DC biased optical OFDM (DCO-OFDM) and asymmetrically clipped DC biased optical OFDM (ADO-OFDM). ADO-OFDM is a new technique that

Performance of Turbo coded wireless link for SISO-OFDM, SIMO-OFDM, MISO-OFDM and MIMO-OFDM system
14th International Conference on Computer and Information Technology (ICCIT 2011), 2011In this paper, performance of a Turbo coded OFDM wireless link is evaluated in the presence of Rayleigh fading for SISO, SIMO, MISO and MIMO system. Data are encoded using turbo encoder then modulated by QPSK or 16 QAM or 64 QAM and further encoded using STBC, and the encoded data are split into n streams which are modulated by OFDM and simultaneously ...

Performance comparison between CI/OFDM and OFDM systems
2010 International Conference on Communications, Circuits and Systems (ICCCAS), 2010Carrier Interferometry Orthogonal frequency division multiplexing (CI/OFDM) has gained a great deal of attention recently because of its good bit error rate (BER) and low peak-to-average power ratio (PAPR) performance. In this paper, we investigate the performance of CI/OFDM based on a new implementation model for both zero forcing (ZF) and minimum ...

Interference Comparison between OFDM & FH-OFDM Systems
Proceedings of the 14th ACM International Symposium on QoS and Security for Wireless and Mobile Networks, 2018Orthogonal Frequency Division Multiplexing (OFDM) is a common modulation technique that is being used in many of modern wireless communications and standards due to its excellent spectral efficiency and immunity to multipath interference in fading channel. In this paper, a Frequency Hopping Orthogonal Frequency Division Multiplexing (FH-OFDM) system is

A OFDM module for a MB-OFDM receiver
2007 International Conference on Design & Technology of Integrated Systems in Nanoscale Era, 2007The rules defined by FFC, for marketing and operation of UWB products, permitted the use of orthogonal frequency division multiplexing (OFDM) to implement UWB communications. MB-OFDM is taking place as good approach to UWB, for instance for wireless USB.
