An equal weight orthogonal (EWO) signalling scheme for wireless infrared code-division multiple access (CDMA) networks is studied. This scheme is primarily suggested to avoid the undesired need of threshold level estimation that is required in on-off keying (OOK)-CDMA systems. The bit error rate (BER) of an EWO-CDMA system, transmitting over non-directed links, is investigated. It is concluded that this signalling method presents an attractive choice due to both its simplicity and its BER performance compared with OOK-CDMA in a multipath infrared media
