Patent ID: 8665693

Claim:
A method for soft interference cancellation, comprising: accepting, by a receiver comprising Mr antennas, a plurality of multicarrier signals substantially simultaneously, wherein the plurality of multicarrier signals comprise N overlapping carrier frequencies, and where Mr and N are integers; removing a cyclic prefix and fast Fourier transforming the plurality of multicarrier signals to yield Mr N-tone signals y; and canceling interference of respective signals of the Mr N-tone signals using a successive SIC (S-SIC) process, wherein the successive S-SIC process comprises: re-encoding and re-modulating soft symbols for respective U layers to yield soft symbol feedback from an i-th iteration for layers, of the U layers, already processed in the i-th iteration, and encoding and re-modulating soft symbols from a (i−1)th iteration for layers, of the U layers, not yet processed in the i-th iteration, where U and i are integers.
