US Patent 11381438 Multiple access schemes with interference mitigation

Methods, systems, and devices for multiple access with interference mitigation are described. A wireless communication method is provided to comprise: generating, from information bits, a modulated signal; spreading the modulated signal using a spreading code to provide a spread data signal; processing the spread data signal through a randomization; and transmitting an orthogonal frequency division multiplexing (OFDM) signal based on an output of the processing.
