Abstract
A receiver, such as a CDMA MIMO receiver, includes a LMMSE-based chip-level equalizer constructed so as to implement a FFT accelerated iterative algorithm having a complexity of order O(N log(N)), where N is the dimension of a covariance matrix. The equalizer uses one of an overlap-save or an over-lap add FFT architecture.
