摘要：Modulating system based on wave filter group includes such as transmitter-processor (20,30) and inverse-fast-fourier-transformating-modules (23,33) and filtermodule (24,34) and includes recipient processor fast-fourier-transformating-modules(40) and (43). Interference is reduced by the filter module (24,34), by in such as

transmitter-processor (20,30), code module (22,32) are introduced with further filteringmodule (26,36) in feedback control loop, and, by introducing decoder module (240 in therecipient processor (40). Splitting-modules (21,31,41) and merging module (25,35,45), toallow using signal stream and parallelism wave filter group. Coding module (22 and 32)respectively include secondary coding module (22-1,22-2,. , 22-a or 32-1,32-2,. , 32-b), filtermodule (24 respectively (220 include secondary filtration modules (221, (222,. , (223, (224,(225,. , (226, further filtering module (227 (the 228 further filtering modules of connector(229,32) 0. including difference.. , 32) and 1 or 32) 2,32) 3... , 32) 4 electrical connection, anddecoded decoder module includes module 32) 5 32) 6 times, 32) 7,. , 32) and 8, all eachsignal streams. Input signal is received in the output of further filtering module or fromthe inverse-fast-fourier-transformating-modules and has been supplied output signaland is encoded the input terminal of the secondary module by subtracting module for

reducing each signal stream interfered via fast-fourier-transformating-modules(Or themodulation system of each subcarrier/subband),Or receive the exports coding from thesecondary module and also supplied the input terminal for outputing signal to thesecondary coding module by subtracting module for reducing each signal streaminterfered(Or between the modulation system of each subcarrier/subband and signalstream(Or in subcarrier/subband)With the so-called slight gap modulating system basedon wave filter group of introducing.
