Abstract:
Wide bandwidth digital pre-distortion (DPD) in a remote unit(s) for a wireless communications system (WCS) is disclosed. In embodiments disclosed herein, a remote unit(s) includes at least two transceiver circuits, each configured to process (e.g., perform DPD) a respective downlink digital communications signal corresponding to a portion of the carrier bandwidth. Each of the transceiver circuits is further configured to convert the respective downlink digital communications signal into a respective downlink RF communications signal. The respective downlink RF communications signals generated by the transceiver circuits are subsequently combined to form a downlink RF communications signal(s) associated with the carrier bandwidth. By employing multiple transceiver circuits in the remote unit(s) to each handle a portion of the carrier bandwidth, it may be possible to mitigate processing bandwidth limitations of the remote unit(s), thus making it possible to satisfy the regulatory and/or operational requirements for supporting wide bandwidth communications in the WCS.
