Message transmission method

摘要

The method involves coding the messages to a signal using orthogonal functions. The orthogonal functions are approximations of Hermite functions. Preferably, the received signal undergoes a Fourier transformation and is decoded using the Hermite functions to get the messages. The received signal is filtered before and after the Fourier transformation preferably by using a low pass filter. The received signal is decoded in the time and in the frequency domain.
