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.

Abstract: In one embodiment, an over-the-air millimeter wave repeater for a communications network comprises: a donor unit including a first plurality of modular electronic components and an access point including a second plurality of modular electronic components. The donor unit communicates downlink mmWave spectrum wireless signals received from a base station to the access point and radiates uplink mmWave spectrum wireless signals received from the access point to the base station. The access point radiates the downlink mmWave spectrum wireless signals received from the donor unit into a coverage area, receives the uplink mmWave spectrum wireless signals received from the coverage area, and communicates the uplink mmWave spectrum wireless signals to the donor unit. The first and second plurality of modular electronic components includes at least one of a modular antenna component, a modular signal conditioning component, a modular signal interface component, and a modular controller.

Abstract: Methods and apparatuses are provided that configure downlink and uplink signal paths by obtaining information about at least one of a downlink filter and an uplink filter in a duplexer unit after the duplexer unit is coupled to a primary uplink signal path and a primary downlink signal path. Based upon such information, at least one component of the downlink and uplink signal paths is adjusted to compensate for the insertion losses of a downlink filter and an uplink filter, where the downlink signal path comprises a secondary downlink signal path in the duplexer unit and the primary downlink signal path, and the uplink signal path comprises a secondary uplink signal path in the duplexer unit and the primary uplink signal path.

Abstract: One embodiment is directed to an open radio access network to provide wireless coverage for a plurality of cells at a site and that comprises a virtualized headend comprising one or more base-station nodes and a plurality of unified remote units deployed at the site. Each of the unified remote units is able to support multiple functional splits, multiple wireless interface protocols, multiple generations of radio access technology, and multiple frequency bands. The unified remote units and functional split used to serve each cell can be changed (for example, on-the-fly as a part of an automatic or manual adaptation process that is a function of one or more monitored performance attributes of the open radio access network such as network bandwidth, network latency, processing load, or processing performance). The unified remote units can be implemented in a modular manner with a backplane to which different radio modules can be coupled.

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.
