Signature sequence selection for CDMA systems with multiple receiver antennas

We consider the problem of signature sequence selection for the uplink of CDMA systems with multiple receiver antennas. We consider the sum capacity, the systemwide MSE, and the effective total squared correlation as performance metrics and formulate iterative algorithms that improve these metrics. The convergence analysis of the algorithms is given and the numerical evidence that supports the analysis is presented along with our observations related to the resulting optimum signature sets.
