Abstract
The present disclosure relates to a transmitter device and a receiver device for a wireless communication system supporting low-overhead multiple access for a layered Fast Fourier Transform-based wireless communication. The transmitter device obtains a plurality of first data symbol matrices in a delay-Doppler domain for a plurality of users, a plurality of second data symbol matrices in an intermediate-frequency domain for the plurality of users, and an aggregated matrix in the intermediate-frequency domain for the plurality of users. The receiver device obtains an aggregated matrix in the intermediate-frequency domain for a plurality of users based on a signal received in a time domain from the transmitter device, a plurality of first data symbol matrices in the intermediate-frequency domain for the plurality of users, and a plurality of second data symbol matrices in the delay-Doppler domain for the plurality of users.
