Abstract :
The wireless CDMA transmitting system using indirectly scattered light is effective for telemetry in a hospital. However, the deterioration of the system performance occurs due to multipath propagation. In this paper, in order to improve the signal deterioration, we introduce the RAKE receiver to the optical telemetry system and evaluate the performance of the system by computer simulations. The obtained results indicates that the proposed system can achieve a BER not exceeding 10-6 in a data-transmitting rate of 300 kbit/s even in the worst case of 5 channel multiplexing with the near-far problem.
