Abstract: Methods, systems, and devices for wireless communications are described. A rateless code may be used to generate n encoded packets based on a set of source packets. A modulation technique may be used to generate first symbol packets from the encoded packets. And a layered modulation technique may be used to generate coded symbol packets from the first symbol packets. The layered modulation technique may include generating a coded symbol packet from a group of first symbol packets. Different weights may be applied to the different first symbol packets included in the group of first symbol packets before the first symbol packets in the group are combined together. A receiving device may demodulate the transmitted coded symbol packets to reconstruct the group of first symbol packets, use the reconstructed group of first symbol packets to recover the encoded packets, and use the encoded packets to reconstruct the source packets.
