Nondirected indoor infrared wireless channel modeling using modulation schemes

The indoor infrared wireless communication has been introduced a new dimension for short range wireless communication. The modulation schemes play an important role during IR channel modeling. The modulation schemes enumerate the harshness of multipath ISI. This paper described and analyzed the various modulations schemes such as on-off-keying(OOK), pulse amplitude modulation (PAM) and pulse position modulation (PPM) and multilevel pulse amplitude and pulse position modulation (PAPM) for the performance measure of Non directed indoor IR channel. It performed the simulation analysis by taking into account the bit error rate (BER) . A fixed rectangular empty room with certain transmitter and receiver geometry was considered during the simulation.
