padm

Version:
    Last Modified: March 15, 2017

    Demodulates a sequence of complex pulse amplitude modulation (PAM) symbols into a series of integers.

    Syntax

    x = padm(y, m)
    x = padm(y, m, phi)
    x = padm(y, m, phi, type)
    Legacy name: pamdemod

    Inputs

    y

    Symbols to demodulate. y is a complex, double-precision, floating-point scalar, vector, or matrix.

    m

    Uses m-ary PAM demodulation. m should be an integer equal to or greater than 2.

    phi

    Initial phase in radians.

    Default: 0

    type

    Method to map symbols to demodulated integers. type is a string that accepts the following values:

    Name Description
    'Bin'

    Uses binary mapping to demodulated integers.

    'Gray'

    Uses Gray-coded mapping to demodulated integers.

    Default: 'Bin'

    Outputs

    x

    Demodulated integers. x is an integer scalar, vector, or matrix in the range [0, m-1].

    X = randint(1, 1000, 8);
    Y = pam(X, 8, 0, 'Gray');
    Z = padm(Y, 8, 0, 'Gray')
