Patent ID: 7693225

Claim:
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; wherein performing frequency-domain equalization includes multiplying each of the N elements with a respective equalization coefficient; and wherein performing interference cancellation for each element a in subset A further comprises: selecting a third subset M and performing inter-carrier interference cancellation for removing the interference caused to element a by the elements in M in current time instant; and selecting a fourth subset P and performing inter-symbol interference cancellation for removing the interference caused to element a by the elements in P in previous time instants.
