Abstract
Systems and methods are described using a Hermetic Transform and inverse Hermetic Transform for transmitting and receiving OFDM signal by replacing a FFT and IFFT with the Hermetic Transform and inverse Hermetic Transform. In an exemplary embodiment, an OFDM transmitter comprises a processor configured to receive a serial signal, divide the serial signal into multiple parallel signals, modulate each of the multiple parallel signals, perform an inverse Hermetic Transform on the multiple parallel signals and provide an output from the inverse Hermetic Transform to RF circuitry for transmission.
