"Webb2 mars 2024 · Hadamard codes are binary {0, 1} sequences that can be used to modulate data by using a fast Walsh–Hadamard transform (FWHT). To simplify the notation, we analyse the signal in one HCM symbol. HCM can be used to support multiple users in a way that is similar to CDMA: the data intended for each user is modulated by one or more … " - Slow-time hadamard coding
