    Abstract: A device may obtain a sequence of input samples. The device may further obtain a first set of sequences, which may be based on discrete prolate spheroidal sequences associated with eigenvalues having a value larger than a first threshold. The device may determine a first projected sample sequence comprising a projection of the sequence of input samples to the first set of sequences and generate a signal based on the first projected sample sequence. Another device may determine a window of received samples of the signal and project the window of received samples to the first set of sequences or filter the window of received samples to obtain a first sample sequence. The detection of the received signal may then be performed based on the first sample sequence.

    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.

    Abstract: The present invention relates to single carrier modulation schemes, and presents a transmitter device, a receiver device and a transceiver device for a single carrier modulation scheme. The transmitter device is configured to generate a plurality of signature roots for a single carrier transmission, construct a Lagrange matrix and a Vandermonde matrix based on the plurality of signature roots, and generate a single carrier modulated signal based on the Lagrange and the Vandermonde matrix. The receiver device is configured to determine a plurality of signature roots, construct at least two Vandermonde matrices from the plurality of signature roots, and perform a demodulation of a single carrier modulated signal based on the at least two Vandermonde matrices. The transceiver device comprising a transmitter device configured to generate a single carrier modulated signal, and a receiver device configured to perform a demodulation of the single carrier modulated signal.
