| Abstract: | Space time multiuser detection based on constrained minimum output energy and its adaptive implementation are studied. This is a blind method which can suppress the multiple access interferences and solve the near far problem without any training sequences. Furthermore, performances of the multiuser CDMA antenna array receiver are analyzed and compared with the performances of the multiuser single antenna receiver, the single user array receiver and the single user single antenna receiver. |

| Keywords: | smart antennas space time processing multiuser detection |
