A system includes an encoding module, a symbol selection module, a subcarrier selection module, and a mapping module. The encoding module receives symbols for transmission over K subcarriers and T antennas, encodes the symbols using a space time code, and generates space time coded (STC) versions of the symbols, where K and T are integers greater than 1. The symbol selection module selects T adjacent ones of the symbols and selects STC versions of the T adjacent ones of the symbols. The subcarrier selection module selects one of the K subcarriers for transmitting the T adjacent ones of the symbols and the STC versions of the T adjacent ones of the symbols. The mapping module maps the T adjacent ones of the symbols onto the T antennas for transmission over the selected one of the K subcarriers, respectively, and maps the STC versions of the T adjacent ones of the symbols onto the T antennas for transmission over the selected one of the K subcarriers.
