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

Implementation of OFDM and Pulsed-OFDM
2016 International Conference on Information Technology (ICIT), 2016This work undertaken, aims to develop pulsed-OFD transmission system, which is used in wide area of wireless communications. It is noteworthy to mention that the system is baseband transmission by excluding the RF (radio frequency) part. Pulsed-OFDM enhances the OFDM that endeavors prominent performance parameters with lesser complexity in ...

Coexistence of UF-OFDM and CP-OFDM
2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016Universal Filtered Orthogonal Frequency Division Multiplexing (UF-OFDM) is considered as a promising 5G waveform candidate. It requires a relatively simple transceiver structure, while achieving much better spectral properties compared to CP-OFDM. During the early deployment of 5G systems, many frequency bands will still be occupied by 4G systems ...

This article discusses the VLSI implications of high-speed coded orthogonal frequency-division multiplexing modulation. This is achieved by looking at practical examples of the computational blocks that constitute a COFDM modem and then examining examples of COFDM chips.

P-OFDM: Spectrally Efficient Unipolar OFDM
Optical Fiber Communication Conference, 2014A novel OFDM signal format, polar-OFDM (P-OFDM), is proposed. P-OFDM offers twice as much spectral efficiency as state-of-the-art real-value unipolar OFDM formats. Inherently, the high PAPR is reduced and the numerical evaluation of the BER performance under dynamic-range constraint of optical sources demonstrates superior results.
