Sample Indexed Spatial Orthogonal Frequency Division Multiplexing
Optical spatial modulation (OSM) is a multiple-transmitter technique that can provide higher data rates with low system complexity as compared to single-input singleoutput (SISO) systems. Orthogonal frequency division multiplexing (OFDM) is widely implemented to achieve better spectral efficiency in wireless channels. Asymmetrically clipped optical OFDM (ACO-OFDM) and DC-biased optical OFDM (DC...
متن کاملAsymmetric Orthogonal Frequency Division Multiplexing
The system described in this paper is an asymmetric adaptation of orthogonal frequency division multiplexing (OFDM). In a conventional OFDM system, the signal processing hardware is divided equally between the base station and the terminal. In the asymmetric system, most of the complex signal processing hardware is shifted to the base station, making the terminal a simpler and more power-effici...
متن کاملOrthogonal Frequency Division Multiplexing Timing Synchronization in Multi-Band Orthogonal Frequency Division Multiplexing Ultra-Wideband Systems
Problem statement: MB-OFDM UWB systems have attractive features and received a great attention. It has the capability of sending/receiving data at rates in access of 100 Mbits sec. Owing to the sensitivity of OFDM systems to synchronization errors, a fast synchronization algorithm is required to discern for the start of OFDM symbol. Existing approaches to OFDM time synchronization rely on their...
متن کاملA Survey: Orthogonal Frequency Division Multiplexing
This paper is a survey regarding the orthogonal frequency division multiplexing. The requirement for high speed data transmission has increased, with the rapid growth of digital communication in recent years. UWB delivers much potential for design of high speed wireless communication system. MB-OFDM (UWB) offers high data rates access for wireless communications. OFDM system is use for high spe...
متن کاملCoherent optical orthogonal frequency division multiplexing
Introduction: Orthogonal frequency division multiplexing (OFDM) has been extensively investigated to combat RF microwave multipath fading, and has been widely implemented in various digital communication standards such as wireless local area network standards (WIFI IEEE 802.11a) [1]. In this Letter, we propose an optical equivalent of the RF OFDM called coherent optical OFDM (CO-OFDM) to combat...
