Patent ID: 11068562

Abstract:
A method and apparatus for fast signal processing is presented. Increase of traffic over data communication networks requires increase of data processing speed. The proposed method is faster than the conventional technique, because it uses less operations of multiplications and additions. The method implements a flexible algorithm architecture based on an elementary cell which is used for both direct and inverse transforms. The method can be implemented for fast analysis and synthesis of different signal types; for fast multiplexing and demultiplexing; and for channel estimation and modeling. The flexible architecture allows: 1) conducting signal analysis according to a certain criterion, and operating on the whole signal or it's part; 2) modifying multiplexed datastream number “on the fly”, splitting and merging groups of datastreams from different sources; 3) splitting a communication channel into a set of subchannels of different bandwidth, organizing data communication in particular subchannels that satisfy certain requirement.
