In this paper, we determine the performances of an Optical Code Division Multiple Access (OCDMA) based wireless transmission system for indoor healthcare monitoring application. We consider line of sight communication links between multiple emitters placed on monitored patients and a base station located at the environment ceiling. We first establish an analytical expression of error probability for...
In this paper, we consider LOS and diffuse transmission schemes for indoor wireless optical communication taking into account the impact of emitter misalignment and mobility by assuming a realistic scenario (random waypoint). We determine the system performance in terms of outage probability and outage capacity. From the results, we show that the maximum achievable rate is obtained for high outage...
In this paper, we study the performance of a Wireless Optical transmission system based on Optical Code Division Multiple Access (OCDMA) to allow multiple user communication. We investigate the impact of user mobility on the LOS and diffuse transmission scheme robustness to Multiple Access Interference (MAI) and near-far effect. For this purpose, we establish an analytical expression of the error...
In the context of healthcare monitoring, it is necessary to transmit vital information from the patient to an interface managed by the hospital staff. In this work we consider a system where the patient can move within a hospital room and the data collected by sensors are transmitted to a distant receiver placed on the ceiling. We investigate the potentiality of using infrared (IR) communication for...

In this paper we investigate performance of indoor Line of Sight (LOS) Wireless Optical Communication (WOC) considering non stationnarity due to emitter and/or receiver mobility. The transmission scheme uses Low Density Parity Check (LDPC) codes to mitigate performance degradation due to mobility. We evaluate a performance bound for LDPC codes in indoor environment and for a given mobility scenario...
