This disclosure describes systems, methods, and devices related to header encoding and modulation. A device may determine an enhanced directional multi-gigabit (EDMG) header field vector comprising one or more bits. The device may determine a first vector associated with a scrambler device, wherein the first vector includes one or more first random bits. The device may scramble the EDMG header field vector based on the first vector. The device may cause to wirelessly transmit to a first device, a codeword associated with the scrambled EDMG header field vector.
