Patent ID: 8837560

Claim:
A method for interference suppression of a signal including one or more symbols, comprising: transmitting each symbol twice in temporal succession as a first symbol and a second symbol so that a segment of the symbol corresponds to a segment of the first symbol and a segment of the second symbol; detecting, by a detector, interference in at least one of (a) the first symbol and (b) the second symbol; transmitting a value to a decision element; and generating, by the decision element, an interference-suppressed symbol from the first symbol and the second symbol on the basis of the value, according to the following decision pattern: in a first segment of a first type, the detector detects interference in the first symbol and an absence of interference in the second symbol, whereupon the decision element sets the interference-suppressed symbol for this segment of the first type to be equal to the second symbol; in a segment of a second type, the detector detects interference in the second symbol and an absence of interference in the first symbol, whereupon the decision element sets the interference-suppressed symbol for the segment of the second type to be equal to the first symbol; in a segment of a third type, the detector detects interference in the first symbol and in the second symbol, whereupon the decision element sets the interference-suppressed symbol for the segment of the third type to be equal to an average value from the first and second symbols; and in a segment of a fourth type, the detector detects an absence of interference in the first symbol and in the second symbol, whereupon the decision element sets the interference-suppressed symbol for the segment of the fourth type to be equal an average value from the first and second symbol; wherein the decision element composes the interference-suppressed signal from the interference-suppressed symbols.
