1. A method of receiving multi-carrier data, the method comprising:

  • receiving a sequence of blocks of frequency domain data comprising N elements, each representing the modulation onto a certain sub-carrier;

    selecting a first subset U among the N elements and performing frequency-domain equalization for each element u in U; and

    selecting a second subset A among the N elements performing both frequency-domain equalization and interference cancellation for each element a in A.
