A method, in a telecommunications system, for transmitting radio signals from a base station comprising at least a pair of transmission branches configured to supply output signals for respective antennae of the base station, to at least one terminal comprising at least one antenna, the method comprising splitting a signal for transmission into at least first and second components, applying a phase shift to the first component to generate a modified first component and providing the modified first component and the second component to respective power amplifiers for transmission over the antennae.

A method includes, in a transceiver (24), receiving from a repeater (32) a received signal, which includes a desired signal for reception and an undesired replica of a transmitted signal that was transmitted from the transceiver and retransmitted by the repeater. A local copy of the transmitted signal is generated in the transceiver. A filter response that, when applied to the transmitted signal before transmission, compensates for a difference in spectral response between the local copy and the undesired replica, is estimated in the transceiver. The undesired replica of the transmitted signal, which is received in the received signal, is matched with the local copy of the transmitted signal, by at least pre-filtering the transmitted signal before transmission with the estimated filter response. Interference caused by the undesired replica to the desired signal is canceled, by combining the local copy and the received signal.

A system for interference mitigation including a transmit coupler that samples the RF transmit signal to create a sampled RF transmit signal; a transmit analog canceller that transforms the RF transmit signal to an RF interference cancellation signal, according to a first configuration state; a first receive coupler that combines the RF interference cancellation signal and the RF receive signal to generate a composite RF receive signal; a sampling analog interference filtering system that, in order to remove interference in the transmit band, filters the sampled RF transmit signal to generate a cleaned transmit signal; a first frequency downconverter that converts the transmit signal to a BB transmit signal; a second frequency downconverter that converts the composite RF receive signal to a composite BB receive signal; and an analog-to-digital converter that converts the transmit signal to a digital transmit signal.

An apparatus, system, and method are provided for energy conversion. For example, the apparatus can include a trans-impedance node, a reactive element, and a trans-impedance circuit. The reactive element can be configured to transfer energy to the trans-impedance node.

The trans-impedance node, as a result, can operate as an RF power switching supply based on the one or more control signals.
