Abstract:
1. An interference suppression system for suppressing an interference signal for a received signal including a plurality of slots having a known series symbol part for estimating a propagation channel and a data part, comprising: block dividing means for dividing said data part of each slot of the received signal into a plurality of blocks; a first channel estimate calculation means for calculating a channel estimate for a current slot of the plurality of slots by using said known series symbol part of a received signal; channel estimate storage means for storing the first channel estimate for the slot calculated at said first channel estimate calculation means; a second channel estimate calculation means for each block for calculating a channel estimate for each block corresponding to each of said plurality of blocks by using a result of primary interpolation between a channel estimate for the current slot calculated at said first channel estimate calculation means and a channel estimate stored for a previous slot in said channel estimate storage means; and suppression means for suppressing said interference signal by performing a calculation for each of said blocks corresponding to said channel estimate for each block by using said channel estimate for each block.
