1. a kind of implementation method of the efficient MWC compression sampling digital receiver structure based on heterogeneous structure, structure integrally useMultichannel form, constructs by MpMultiple branch structures of a mixing element and multiphase filter structure composition, connect in original MWCAbstraction module is advanced to the front end of entire digital receiver in receipts machine structure basis, i.e., filter is advanced to by withdrawal deviceWithdrawal device is moved forward to branch by the corresponding relationship of data and mixing sequence main value element after preceding identical transformation relationship and extractionDigital mixing element is added in front end in original multiphase filter structure, and whole MWC branch structure is included in heterogeneous structureIn, multiple road combined to constitute the whole efficient MWC compression sampling digital receiver based on heterogeneous structure, each of themBranch all includes three modules:

  • Serioparallel exchange module, parallel multiplication module and multiphase low-pass filtering module, it is characterised in that:

    InstituteDiscretization signal data is converted into M by the serioparallel exchange module statedpChannel parallel data is spaced M between the data of two, every roadpA memberElement;

    The every circuit-switched data for the parallel data that parallel multiplication module exports serioparallel exchange module and corresponding mixing element multiplication, it is completeAt mixing operation, signal is mixed on all subbands and exports the data after mixing and give multiphase low-pass filtering module;

    It is moreThe data after mixing in phase low-pass filtering module carry out convolution algorithm with per filter coefficient all the way, thus by the letter of base bandIt number filters out, finally obtains the output of a branch of efficient multiphase MWC digital receiver;

    The Comparative result of multiple-channel output is asked againThe original sub-band number where signal is obtained, thus the reception of complete pair signals.
