Abstract

A new technique, which can increase the data rate in optical orthogonal frequency division multiplexed access link, is proposed in this paper. An adaptive sampling based on a compressive sensing (CS) technique is implemented in order to save channel bandwidth. The CS tells us that all signals with high sparsity, which is sampled below the Nyquist/Shannon limit, can be reconstructed successively using sufficient measurement. In this paper, it is reported that the compression ratio of 40% is observed within the error free optical transmission (FEC limit: BER of 10^-3) in case of QPSK symbols. It means that its data rate can be increased by 1.7 times (from 1.56 to 2.3 Gbps) using the proposed technique without the use of optical and electrical devices with higher physical bandwidth.
