1. A method for combining a plurality of downlink signals representative of a communication signal, the method comprising:
receiving the plurality of downlink signals from a plurality of antenna feeds;
in a first one or more processing blocks in a one or more processors,
performing a first blind detection operation on first data packets of a first signal of the plurality of downlink signals, and
performing a first doppler compensation operation on the first data packets of the first signal of the plurality of downlink signals;
in a second one or more processing blocks in the one or more processors in parallel with the first one or more processing blocks,
performing a second blind detection operation on second data packets of a second signal of the plurality of downlink signals, and
performing a second doppler compensation operation on the second data packets of the second signal of the plurality of downlink signals; and
combining the first signal and the second signal based on (i) aligning timing and phase of the first data packets with the second data packets and (ii) performing a weighted combiner operation that applies scaling to each of the first and second data packets based on corresponding signal quality.
