Abstract
Methods, apparatuses, and systems to enable a channel estimation of more than one channel for Multi-Input Multi-Output (MIMO) communications in a wireless network is provided. The method includes determining a first set of complex numbers comprising first channel estimation signal associated with a first channel, determining a second set of complex numbers comprising second channel estimation signal associated with a second channel, and transmitting the first set of complex numbers and the second set of complex numbers via a physical layer (PHY) frame, wherein the second set of complex numbers are complex conjugates of the first set of complex numbers.
