| 520 | _aIn this thesis, we introduce an indoor optical wireless communication system that enhances the system capacity and mitigates the interference in the optical cell. The main objective of this work is to improve the signal to interference noise ratio (SINR) and the system reliability.The thesis is separated into main three parts: optical modulation, resource allocation and interference management algorithms. In the optical modulation, we introduce a multi carrier optical modulation technique that enhances the spectral and power efficiency for real constellation modulation techniques. As it uses all the available subcarriers to send an odd real data and clips the negative parts. In the resource allocation, we propose an optimized resource allocation technique with rate and power constraints that maximizes the total output data rate while satisfying the constraints and enhancing the computational complexity. By allocating power and subcarriers to each user depending on its SINR and rate constraint, respectively. In the interference management, we introduce an interference management algorithm that mitigates the inter cell interference at the cell edge. As the frequency band is divided into reused band that is used in the cell area and shared band that is used in the interference area | ||
