Abstract:
1. A transceiver for self-interference suppression, comprising, within one transceiver device: two or more transmitters comprising one or more signal generators for transmitting transmit signals having transmit center frequencies in a selected first subchannel, wherein each of the two or more transmitters is dedicated for a different antenna; and a receiver corresponding to the same antenna as one of the two or more transmitters and having receiver inputs for simultaneously receiving a desired receive signal in a second subchannel and an undesired accumulated interference signal due to said transmitted signals from the two or more transmitters; wherein at least one of said transmitters that is associated with an antenna other than the antenna corresponding to the receiver is associated with a precompensation circuit that modifies the transmit signals such that said accumulated interference signal at the receiver inputs is reduced.
