An efficient dynamic digital channelizer
SI Xi-cai · Ha'erbin gongye daxue xuebao · 2009
An efficient dynamic digital channelization method was proposed to deal with the problem of the existance of multi-channels non-uniformly distributed and dynamically changed in wideband received signal.This method is based on signal reconstruction theory.It splits the received signal into uniformly sub-bands,then puts the adjacent sub-bands of the same channel into a special synthesis filter bank,and the output is the baseband signal of this channel.When the number of sub-bands is changed,coefficients of the synthesis filter banks are changed according to the results of energy detection.It is proved that the channelization method is adaptive.
