The DUC block upsamples the input signal using a cascade of three interpolation filters. /Dest [ 7 0 R /FitH 416 ] /Parent 33 0 R /Prev 43 0 R /Next 41 0 R >> endobj 43 0 obj << /Title (The Digital Down Converter or DDC) /Dest [ 32 0 R /FitH 380 ] /Parent 33 0 R /Prev 34 0 R /Next 42 0 R /First 44 0 R /Last 44 0 R /Count 4 >> endobj 44 0 obj << /Title () /Dest [ 1 0 R /FitH 799 ] /Parent 43 0 R /First 45 0 R /Last 45 0 R /Count 3 >> endobj 45 0 obj << /Title () /Dest [ 1 0 R /FitH 799 ] /Parent 44 0 R /First 46 0 R /Last 46 0 R /Count 2 >> endobj 46 0 obj << /Title () /Dest [ 1 0 R /FitH 799 ] /Parent 45 0 R /First 47 0 R /Last 47 0 R /Count 1 >> endobj 47 0 obj << /Title (How It Works) /Dest [ 1 0 R /FitH 799 ] /Parent 46 0 R >> endobj 48 0 obj << /ProcSet [ /PDF /Text /ImageC /ImageI ] /Font << /F1 52 0 R /TT2 54 0 R /TT4 49 0 R /TT6 55 0 R /TT8 70 0 R >> /XObject << /Im1 78 0 R /Im2 79 0 R >> /ExtGState << /GS1 75 0 R >> /ColorSpace << /Cs5 57 0 R /Cs9 56 0 R >> >> endobj 49 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 85 /Widths [ 250 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 667 0 722 778 389 0 0 0 0 722 0 0 0 667 0 611 722 ] /Encoding /WinAnsiEncoding /BaseFont /TimesNewRoman,BoldItalic /FontDescriptor 51 0 R >> endobj 50 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 0 /Descent -216 /Flags 34 /FontBBox [ -558 -307 2034 1026 ] /FontName /TimesNewRoman,Bold /ItalicAngle 0 /StemV 133 >> endobj 51 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 0 /Descent -216 /Flags 98 /FontBBox [ -547 -307 1206 1032 ] /FontName /TimesNewRoman,BoldItalic /ItalicAngle -15 /StemV 133 >> endobj 52 0 obj << /Type /Font /Subtype /Type1 /Encoding /WinAnsiEncoding /BaseFont /Courier >> endobj 53 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 0 /Descent -216 /Flags 34 /FontBBox [ -568 -307 2028 1007 ] /FontName /TimesNewRoman /ItalicAngle 0 /StemV 0 >> endobj 54 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 150 /Widths [ 250 333 0 0 0 0 0 0 333 333 0 0 250 333 250 278 500 500 500 500 500 500 500 500 500 500 278 278 0 0 0 444 0 722 667 667 722 611 556 722 722 333 0 722 611 889 722 722 556 0 667 556 611 722 722 944 722 722 0 0 0 0 0 0 0 444 500 444 500 444 333 500 500 278 278 500 278 778 500 500 500 500 333 389 278 500 500 722 500 500 444 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 333 444 444 0 500 ] /Encoding /WinAnsiEncoding /BaseFont /TimesNewRoman /FontDescriptor 53 0 R >> endobj 55 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 121 /Widths [ 250 0 0 0 0 0 0 0 333 333 0 570 250 333 250 278 500 500 500 0 500 0 500 500 500 500 333 0 0 0 0 500 930 722 667 722 722 667 611 0 778 389 0 778 667 0 0 0 611 0 722 556 667 722 0 1000 0 0 0 0 0 0 0 0 0 500 556 444 556 444 333 500 556 278 0 556 278 833 556 500 556 556 444 389 333 556 500 722 500 500 ] /Encoding /WinAnsiEncoding /BaseFont /TimesNewRoman,Bold /FontDescriptor 50 0 R >> endobj 56 0 obj [ /Indexed 57 0 R 255 76 0 R ] endobj 57 0 obj [ /CalRGB << /WhitePoint [ 0.9505 1 1.089 ] /Gamma [ 2.22221 2.22221 2.22221 ] /Matrix [ 0.4124 0.2126 0.0193 0.3576 0.71519 0.1192 0.1805 0.0722 0.9505 ] >> ] endobj 58 0 obj 942 endobj 59 0 obj << /Filter /FlateDecode /Length 58 0 R >> stream 3 0 obj An improved resource-efficient DDC with polyphase architecture and distributed arithmetic (DA) is presented in this paper.
