Abstract :
We study the uplink performance of wireless infrared code-division multiple access (CDMA) networks using OOK with optical orthogonal codes (OOC´s). The analysis is performed in two cases assuming a cellular network architecture, in which all users are uniformly distributed in the cell´s area. The first case is when all users transmit with the same power and no power control mechanism is used. Then, the system that deploys power control mechanism is analyzed and the performance improvements are demonstrated. The impact of imperfect power control which is caused by errors in channel estimation is also analyzed and the analytical and numerical results for all cases are included. The results clearly demonstrate the advantages of using power control algorithms for indoor infrared wireless systems that use OOC modulation techniques
