Abstract:
1. A method for transmitting information in a communication system in which information is transmitted in the form of symbols represented by signals, and in which the duration of the signals is longer than the time period between the start of one symbol and the next, comprising the steps of: a) synthesizing waveforms from stored digital data representing waveforms resulting from a summation of overlapping signals, the stored digital data representing waveforms being stored in a memory comprising a number of cells; b) transmitting the synthesized waveforms; and when data is read from the memory during transmission, address lines are used to select a cell to be accessed, and the stored digital data is organized in the memory in such a way that when the data is read out the values sent on a first set of address lines depend on the sequence of overlapping signals currently being transmitted, and the values sent on a second set of address lines depend on the number of cells that have already been accessed since the most recent start of transmission of a signal.
