Code division multiple access (CDMA) has been shown to offer higher capacity than the existing FDMA or TDMA systems. In the proposed IS-95 CDMA standard, no pilot is used in the reverse link due to power efficiency considerations. Therefore, an M-ary orthogonal modulation with noncoherent reception is used for this link. Spatial processing with base-station antenna arrays was proposed to reduce co-channel interference and increase system capacity. We present a base-station antenna arrays receiver structure for cellular CDMA with M-ary orthogonal modulation and noncoherent RAKE combining in the presence of multipath.<
