A wireless communications device includes an encoder having an input for receiving an input symbol, and generates based upon the input symbol a channel symbol and an antenna control symbol. At least one transmitter is coupled to the encoder for receiving the channel symbol. An antenna switch is coupled to the encoder for receiving the antenna control symbol, and to the at least one transmitter for receiving the channel symbol to be transmitted. An antenna array is coupled to the antenna switch and includes N antenna elements, with N = 2. The antenna switch selects less than N antenna elements based upon the antenna control symbol for transmitting the channel symbol.
