| Abstract: | In this paper, we consider a kurtosis-based optimization criterion and then present a blind adaptive decorrelating detector in the multipath CDMA channels. We show that the solution to the optimization problem satisfies the zero-forcing condition, which is also the solution achieved by the decorrelating detector. 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 presented detectors. |
