Phase Shift Keying Modulator (PSKMOD)

 

 


Property

Description

Units

Default

Range

M

The order of the signal space.
M = 2: BPSK

M = 4: QPSK, etc.

None

2

[2, 128]/Integer

RIN

Input impedance

Ohm

Inf

(0, Inf]

ROUT1

Output impedance

Ohm

0

[0, Inf)

ROUT2

Output impedance

Ohm

0

[0, Inf)

Ports

Input

Input signal of symbols in the range 0,....., M -1 ( integer)

Output1

The real part of the complex output signal (real)

Output2

The imaginary part of the complex output signal (real)

 

Notes

1. This model maps the integer input symbols, each in the range 0,...., M -1, into a complex (real and imaginary) output value. The complex value of the output is given by
exp(j* 2*PI*k/M) M = 2
exp(j* 2*PI*(k+1/2)/M), M = 4, 6, 8, ..

Netlist Form

PSKMOD n1 n2 n3 M=val [Rin=Val] [Rout=Val]

Netlist Example

PSKMOD:1 1 2 3 M=4
