Bit interleaving for bitwise autoencoder based communications

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may train a bitwise autoencoder neural network to obtain a constellation mapping. The WCD may determine a bit position ordering for bit positions of modulated symbols associated with the constellation mapping based at least in part on error protection levels of bit positions associated with the constellation mapping. The WCD may perform bit interleaving for one or more coded bits of a communication, based at least in part on the bit position ordering of the constellation mapping, to obtain one or more interleaved bits. The WCD may generate one or more modulated symbols for the communication by mapping the one or more interleaved bits using the constellation mapping. The WCD may transmit, to a receiver device, the one or more modulated symbols for the communication. Numerous other aspects are described.
