A new pulse position modulation code division multiple access (PPM-CDMA) system is proposed for an indoor optical wireless channel. As a signature sequence for CDMA an optical orthogonal code (OOC) is used. To reduce multiple access interference two interference cancellation schemes are employed: decorrelating detection and successive interference cancellation (SIC). The bit error rate of the proposed system is calculated for a conventional receiver, a decorrelating receiver, and a receiver with SIC. It is shown that PPM-CDMA systems with both decorrelating detection and SIC achieve significant SNR improvement over the system with a conventional receiver
