Abstract
Asynchronous multirate pulse position modulation-code division multipl e access (PPM-CDMA) is proposed for an indoor optical wireless lime di spersive channel. As a signature sequence for CDMA, an optical orthogo nal code (OOC) is used. The optical PPM-CDMA has advantages in that it is power efficient and provides multirate services by simply varying the modulation level for the fixed chip rate at the transmitter and sa mpling time at the receiver.
