    Abstract: A method is provided. The method, comprises: power amplifying, with at least two parallel power amplifiers, at least two pre-distorted signals each corresponding to a unique transmit band, wherein each power amplifier operates in a unique transmit band; and pre-distorting, with a single pre-distortion system, at least two signals in different transmit bands, where the pre-distortion of each of the at least two signals is based upon a portion of a corresponding power amplified, pre-distorted signal, and where the pre-distortion diminishes certain IMD products in the corresponding power amplified, pre-distorted signal.

    CPC classification number: H04L27/2623

    Abstract: To provide improvements in crest factor reduction in a distributed communication system, CFR configuration parameters can be determined based on communication signals received from a base station entity and distributed to node(s) of the distributed communication system. CFR engine(s) in the node(s) may perform CFR based on the CFR configuration parameters, and/or may adjust their CFR engine(s) based on signal parameters and/or operating parameters of a power amplifier coupled to a respective CFR engine. Some or all CFR processing may be offloaded from a node and assigned to optical transport card(s) of the system controller based on a processing bandwidth associated with the optical transport card(s).

    Abstract: In one embodiment, a multi-transceiver RF signal processing system comprises: a controller; a DPD core and CFR engine; and a plurality of transceiver paths comprising at least a first transceiver path for a first frequency block, and a second transceiver path for a second frequency block. The first frequency block is adjacent to the second frequency block. Signal processing outputs a stream of digital RF based on wireless RF signals received into the first and second transceiver paths. Signal processing inputs a first stream of digital RF and outputs a first digital RF signal corresponding to the first frequency block to the first transceiver path, and outputs a second digital RF signal corresponding to the second frequency block to the second transceiver path for wireless transmission via the at least one antenna. The DPD core applies a distortion that covers the first and second frequency blocks.

    Abstract: A distributed antenna system includes a master unit configured to receive at least one set of multiple input multiple output (MIMO) channel signals from at least one signal source. The master unit is configured to frequency convert at least one of the MIMO channel signals to a different frequency from an original frequency, and combine the MIMO channel signals for transmission. An optical link couples the master unit with a unit remote from the master unit for transceiving the MIMO channel signals. Conversion circuitry is configured to frequency convert at least one of the first and second MIMO channel signals from the different frequency back to an original frequency for transmission over an antenna.
