摘要：
In this paper, we consider a kurtosis-based optimization criterion by employing the decision-directed sequence to generate a cross-correlation penalization term and show that the solution to the optimization problem satisfies the zero-forcing condition. Hence we present a kurtosis-based blind adaptive decorrelating detector in the multipath CDMA channels. By use of gradient-descent method, an adaptive algorithm to solve the optimization problem is given. Finally, simulation examples are given to demonstrate the performance of the kurtosis-based detectors.
