Claim:
1. A method for transmitting digital data in a transmit symbol using a generalized frequency divisional multiplexing (GFDM) system, the transmit symbol comprising a plurality of data symbols assigned to at least two subcarriers, the method comprising: mapping a plurality of data bits to data symbols and assigning data symbols to the at least two subcarriers; spreading the information of each data symbol of a time slot of the transmit symbol across the data symbols of each subcarrier of the time slot, wherein a transformation matrix to all data symbols of the time slot is applied, wherein the rows and columns of the transformation matrix are orthogonal; appending at least one of a cyclic prefix or a cyclic suffix to the transmit symbol; and transmitting the transmit symbol and the cyclic prefix and/or the cyclic suffix.
