Abstract
A method and apparatus for performing joint channel equalization (JCE) are disclosed. JCE is implemented to reject inter-cell and intra-cell interference in a receiver. The JCE only requires the channel responses of a desired signal and interferers with respect to different antennas. In order to implement JCE, a number of discrete Fourier transforms (DFTs) and an inverse discrete Fourier transform (IDFT) are performed and a number of independent linear systems are solved. With M antennas, the JCE is capable of completely rejecting M−1 interferers. Over-sampling with diversity may be used to increase observation dimensions to a certain extent so that a receiver with M antennas may be able to reject more than M−1 interferers.
