Paper Abstract

This paper considers the design of a common collector common emitter PPM PIN-BJT receiver to achieve a good sensitivity improvement in the indoor infrared wireless communication system. The system operates at a bit rate of 10 Mbit/s and (lambda) equals 0.85 micrometers . The results demonstrate a low noise current for the receiver of about 2.7 pA/ (root)Hz. Original results are presented illustrating the systems to achieve a sensitivity of -50.5 dBm at an error rate of 10-9 representing an improvement of 9.8 dB over a comparable ON OFF keying PIN-BJT system. The sensitivity enhancement has significant impact on the optical wireless network where the maximum allowed transmitted power is limited by safety issues. Moreover, the use of PPM offers other advantages such as the low average power which is suited for battery operation and a high peak power that aids detection.
