Abstract: Embodiments of systems and methods for combining downlink signals representative of a communication signal are provided herein. An example method comprises receiving samples of the downlink signals from multiple antenna feeds; generating first symbols for a first signal and second symbols for a second signal based on performing timing recovery operations on the first signal and the second signal, respectively; generating offset information based on performing a correlator operation on the first and second symbols; and combining the first and second signals based on performing a weighted combiner operation. At least one of the first timing recovery operation, the second timing recovery operation, the correlator operation, and the combing are performed in a plurality of processing blocks in one or more processors, wherein the first and second processing block operate in parallel.
