1. A method of transmitting signals, the method comprising:
forming first signals based on data by encoding portions of the data according to a first encoding scheme to form first encoded data, mapping the first encoded data to first symbols according to a first modulation scheme, and performing an inverse discrete Fourier transform and multiplication by a complex waveform on the first symbols to form the first signals;
forming second signals based on data by encoding portions of the data according to a second encoding scheme to form second encoded data, mapping the second encoded data to second symbols according to a second modulation scheme, and performing an inverse discrete Fourier transform and multiplication by a complex waveform on the second symbols to form the second signals;
transmitting signals using one or more first subcarriers only from a first antenna, wherein the signals transmitted from the first antenna comprise first signals based on data; and
transmitting signals using one or more second subcarriers different from the one or more first subcarriers only from a second antenna, wherein the signals transmitted from the second antenna comprise second signals based on the data;
wherein the data comprises one or more data portions;
wherein the transmitting the signals from the first and second antennas comprises, for each data portion, transmitting at least one first symbol using a respective one of the one or more first subcarriers from the first antenna, and transmitting at least one second symbol using a respective one of the one or more second subcarriers from the second antenna; and
wherein the first symbol and the second symbol are identical.
