Abstract (en)
[origin: WO0161910A1] The invention relates to a system for the transmission of data, by means of a number (N) of transmission channels, formed by discrete carrier frequencies, on a line (10) between a central site (1) and a number of users (2, 3,..., 8, 9), connected to the line at various branch points, with a transmit and receiver unit (11), arranged at the central site (1) and transmit and receiver units (18, 19) associated with each user (2, 3,..., 8, 9). The transmission units each comprise a multiplex unit (50), to divide the data stream into data blocks, coding units (21, 22, 23, 24), an inverse fourier transformation filter bank (20), formed from several identical prototype filters (30, 31, 32, 33), decoder units (41, 42, 43, 44) and a demultiplexer unit (50). The processing of the data stream for transmission is carried out within the inverse fourier transformation filter bank and the fourier transformation filter bank, with a block length (M), whereby the block length (M) is larger than the number of transmission channels (N).
