CANCELLATION OF INTERFERENCE IN MULTICARRIER RECEIVERS |
摘要 |
Signals are transmitted on sub-channels at different but mutually overlappin g frequencies. A receiver separates the sub-channels into component signals z0...c254 Prior to decoding (7), interfere nce estimates c0...c254 are subtracted from the components. These estimates are deduced from the signals received on the idle sub-channels (or on sub-channels from which a known or estimated signal is subtracted), for example by calculating (10) parameters defining a model of the interference and using these (11) to generate the interference estimates.
