Since 2, 3, 4 ,... 8 SS are each independently optional yet are rendered as one line iterm, therefore such coupling does not imply both LDPC TX and RX must both be implemented or not. Really this language is used to indicate that LDPC is never mandatory, and so the language does not preclude the full range of implementations enabled by the VHT Capabilities IE. VHT PHY data subcarriers are modulated using binary phase shift keying (BPSK), “The quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (16-QAM), and 256-QAM.
