A recently granted patent (Publication Number: US11863284B2) discloses a method for combining multiple downlink signals representing a communication signal. The method involves receiving samples of these signals from various antenna feeds, generating symbols for each signal through timing recovery operations, determining time and phase offset information using a correlator operation, and combining the signals based on aligned timing and phase, as well as signal quality scaling. The processing blocks for timing recovery, correlator operation, and combining are performed in parallel by one or more processors, potentially including multiple CPU cores or processors for efficient operation.

Furthermore, the patent also describes a system and an apparatus for implementing this method, utilizing a plurality of antennas to receive downlink signals and one or more processors with processing blocks to carry out the necessary operations. The system and apparatus also employ single instructions, multiple data (SIMD) techniques to enhance throughput. The disclosed method, system, and apparatus aim to efficiently combine downlink signals for improved communication signal processing, with a focus on parallel processing and optimized resource utilization for enhanced performance in communication systems.
