A user equipment (UE) in a wireless network employs orthogonal polyphase codes for encoding data symbols to generate a set of coded data symbols, which are modulated onto Orthogonal Frequency Division Multiplex (OFDM) subcarrier frequencies assigned for use by the UE, and the resulting OFDM signal is transmitted to a base station in the wireless network. The orthogonal polyphase codes include pairs of orthogonal polyphase codes that are complex conjugates of each other.
