Performance analysis for Adaptive Subcarriers Allocation in Coherent Optical OFDM System
نویسندگان
چکیده
The constraint to satisfy the need of increased bandwidth requirement for high speed applications with higher performance has been a motivation to work on Optical Orthogonal Frequency division multiplexing (OOFDM) technique with coherent detection. We implement the coherent optical OFDM (CO-OOFDM) technique and investigate the effect of the number of sub-carriers on performance over single mode fiber (SMF) links. To explore improvement in performance adaptive subcarriers has been selected by assigning subcarriers to user according to the conditions of channel. An adaptive subcarrier allocation has been investigated and performance comparison for proportional and equal allocation has been carried over.

Multi-User Adaptive Resource Allocation Scheme for WLAN OFDM-MIMO Transmission
. Orthogonal Frequency division multiplexing (OFDM) has recently been proposed for use in high data-rate wireless systems. OFDM has an important property of spectrum utilization technique that distributes each tone, which is orthogonal with every other tone. The system capacity can be significantly improved by multiple transmit and receive antennas that are used to form Multi-input multi-output...

In this paper, we propose a novel scheme of orthogonal frequency division multiplexing (OFDM) for intensity modulation direct detection (IM/DD) optical systems. By using this novel scheme of an OFDM optical system, not only odd subcarriers but also even subcarriers can be modulated to transmit a clipping optical signal. A conventional asymmetrically clipping optical (ACO)-OFDM is applied to mod...
