Full textThe field of the remote monitoring has experienced significant advancements in recent decades, and now covers different contexts, such as hospitals, retirement homes, and private homes also. The majority of existing systems are based on radio frequency technology (RF).We propose in this thesis, research focused on remote monitoring in a new context involving a nursery. Given the limitations of RF technology, including the impact of electromagnetic interference, and security vulnerabilities, an alternative solution is optical wireless communication technology. Therefore, we investigated the use of infrared technology for simultaneous transmission of data collected from sensors placed on the foot of baby beds, and also on the babies themselves lying in their beds within the nursery. The reception system consists of photodiodes positioned at the corners of a central lighting panel on the celling. The channel simulation carried out using ray-tracing and Monte-Carlo methods was used to determine the channel gain for each device. Several deployment scenarios were defined, considering the nature of the devices (removable or fixed) and the interchangeability of beds in the room. The channel sharing employs the code division multiple access (OCDMA) associated with the optical orthogonal codes (OOC) with the primary constraint being the137 multiple access interference (MAI). The performance of binary pulse position modulation (2- PPM) with OCDMA and soft decoding in reception was studied theoretically and by simulation involving the different scenarios. These scenarios consider a network of 11 users, consisting of 8 beds and 3 devices carried by babies. Results were obtained using the conventional correlation receiver without and with hard limiters, as well as a parallel interference cancellation receiver to reduce the impact of MAI. Additionally, the feasibility of implementing OCDMA technology for simultaneous optical wireless communication transmission was demonstrated through experimental work using a test bench developed in software-defined radio. The test bench was established using universal software radio peripheral (USRP), and specially designed wireless optical front-ends

Full textWe investigate pulse position modulation (PPM) and multipulse PPM (MPPM) for free space op- tical channels using bit interleaved coded modulation with iterative decoding. Data bits are first encoded by using a non recursive convolutional code and the coded bits after an interleaver are modulated before transmission. Iterative decoding is performed at the receiver. Optimized mapping is designed for MPPM. A genetic algorithm is used to find the optimized mapping for MPPM. Our simulation results show that a significant improvement in the error performance can be achieved by using optimized mapping and iterative decoding at the receiver.
