Abstract:
1. A method for reducing interference between a main device that transmits information on sub-carriers having frequencies belonging to a main band of frequencies, the information based upon symbols obtained by a mapping of a punctured stream of bits according to a modulation mapping scheme, and at least one auxiliary device that at least one of emits and receives information within an auxiliary band of frequencies, the auxiliary band of frequencies being narrower than the main band and included within the main band, the method comprising: performing a main interference reduction mode within the main device and comprising a detection step for detecting at least one of an emission from and a reception performed by the at least one auxiliary device; determining from the detection step at least one interfering sub-carrier interfering with the auxiliary band of frequencies; determining bits of the punctured stream of bits which correspond to the information carried by the at least one interfering sub-carrier; and processing the determined bits to generate processed bits mapped to a reference symbol having an amplitude within a threshold of zero, with a control indication being associated to each determined bit, and with bits associated with the control indication being mapped to the reference symbol.
