The Design of Integer Modulated Fir Filter Banks

In this papcr, a mcthod of designing integer M-channel rxioddatcd filter banks satisfying pcrfect rcconstruction is proposcd. Using this mctliod, modulation vcctors and prototypo filter ran bc both rcprescntcd using iutcgcr valucs, which givw thc advantage of fast conipiitation and easy implcmcntation. Experimental rcsiilts show that the coding gain pcrforniance, calculatcul bad 0x1 thc AR(1) signal model, is clw to that of rcd-valued cosinomodiilatcd filtcr banks with the same ordcr.
