Depuncturer (DPUNC)

Depuncturer (DPUNC)

Property	Description	Units	Default	Range/Type
N	Puncturing period	None	4	[1, Inf)/Integer
RIN1	Input impedance	Ohm	Inf	(0, Inf]/Real
RIN2	Input impedance	Ohm	Inf	(0, Inf]/Real
ROUT	output Impedance	Ohm	0	[0, Inf)/Real
Ports
Input1	Received signal before depuncturing (real)
Input2	Puncturing pattern (integer)
Output	The signal after depuncturing (real)

Notes

1. This model can be used to perform the inverse procedure of “Puncturing”. Depuncturing is done by simply inserting dummy bits into the locations that were punctured at the output of convolutional encoder. The value of dummy bits is set to “zero” in this model. Please refer to the Puncturer model for details.

Netlist Form

DPUNC:NAME n1 n2 n3 N=val [RIN1=val] [RIN2=val] [ROUT=val]

Netlist Example

DPUNC:1 1 2 3 N=6
