Abstract The use of adaptive antennas in cellular mobileradio systems is considered to be one of the mostimportant measures to increase capacity. The consideredadaptive antenna concept is applied to the well-known TD-CDMA mobile radio air interface. TD-CDMA isadopted by ETSI for the UTRA TDD mode and is one of thecandidates considered by ITU for IMT-2000. In thereceivers of a TD-CDMA system the intracell multiple access interference (MAI) is eliminated byjoint detection. This detection algorithm also offersthe advantageous possibility of considering theintercell interference covariance matrix in order toenhance system performance. In this paper, amulti-antenna receiver structure with the capability toestimate the covariance matrix of the received intercellmultiple access interference (MAI) is presented. The benefits of taking into account theinterference covariance matrix both in channelestimation and data detection are shown by simulations.The directional channel models applied in thesimulations are derived from measured channel impulseresponses.
