Abstract
In this paper, we demonstrate an experimental study on the use of visible light communications (VLC) for downhole gas pipeline telemetry/monitoring systems. To emulate real field conditions, an experimental setup is created, which consists of a carbon steel coated gas pipeline, a receiving detector, and a transmitting light source such that the medium possesses properties of nitrogen gas. The performance of a VLC system employing an asymmetrically clipped optical orthogonal frequency division multiplexing modulation technique is practically tested by taking channel estimation and synchronization into account. The implementation is tested for a quadrature phase-shift keying modulation technique with a sampling rate of 2 Mbps. The channel impulse response is presented along with a proposed path-loss model. As a performance metric, the system's signal-to-noise ratio (SNR) against bit-error-rate (BER) behavior is investigated for nitrogen gas at atmospheric pressure. The results of the free-space air medium are also included as a benchmark.
