1. A method for modulating a satellite downlink signal representative of a communication signal, the method comprising:
receiving an input signal in the form of a digital bit stream;
splitting the digital bit stream into data packets, each of the data packets including an overlap of data from an adjacent packet;
in a first one or more processing blocks in a one or more processors,
performing a first modulation operation on first data packets of the data packets based on a modulation scheme for a receiver of the downlink signal to create modulated first data packets;
in a second one or more processing blocks in the one or more processors in parallel with performing the first modulation operation in the first one or more processing blocks,
performing a second modulation operation on second data packets of the data packets based on the modulation scheme for the receiver of the downlink signal to create modulated second data packets, wherein the second modulation operation is the same as the first modulation operation;
combining the modulated first data packets and the modulated second data packets in an order which corresponds to the order in which the digital bit stream was received; and
generating a waveform as the downlink signal based on the combined modulated first data packets and the modulated second data packets.
