This disclosure describes the generation and implementation of Golay sequences and Golay Sequence Sets (GSSs) for channel estimation in wireless networks. In one embodiment, this disclosure describes an extension of the Golay sequences Ga and Gb defined in various legacy standards to GSSs. In various embodiments, the disclosed GSSs can include a number of Golay complementary pairs (e.g., Ga and Gb). In one embodiment, the disclosed Golay complementary pairs can meet various predetermined design rules and can be used to define enhanced directional multi-gigabit (EDMG) short training field (STF) and/or channel estimation field (CEF) fields for multiple-input and multiple-output (MIMO) transmission.
