<p>The present method provides for coding information data by using Hermite polynomials and OFDM modulation.
Whenever a signal is coded using Hermite polynomials, the resulting pulse in the time domain is leaving enough time free to allow an additional signal to be transmitted. It is therefore possible to time division multiplex a second signal together with the OFDM original signal which has been coded with Hermite polynomials.
Further a Gaussian windowing can be used to reduce the signal bandwidth and OFDM orthogonality can be assured by mathematical equations.
