Abstract
A novel two-dimensional diversity combining is proposed for the uplink in a single cell that employs multidimensional multicode DS-CDMA signaling and two receive antennas. First, the signaling is combined with preceding to obtain a constant envelope signal that is suitable for the uplink, and the resulting error detection is applied to the diversity combining. Based on the error detection, an adaptive selection combining/maximal-ratio combining (SC/MRC) is performed for which initial data detection is made by the SC to avoid the combining loss of the very noisy paths. Further, this adaptive SC/MRC is generalized to maximize the diversity gain over the MRC, offered by the error detection capability.
