pulpy.rf.slr.dz_hadamard_b(n=128, g=5, gind=1, tb=4, d1=0.01, d2=0.01, shift=32)

Design a pulse with hadamard encoding

Parameters:

• n (int) – number of time points.

• g (int) – order of the Hadamard matrix.

• gind (int) – index of vector to use from Hadamard matrix for encoding.

• tb (int) – time bandwidth product.

• d1 (float) – passband ripple level in :math:’M_0^{-1}’.

• d2 (float) – stopband ripple level in :math:’M_0^{-1}’.

• shift (int) – n time points shift of pulse.

Returns:

SLR beta parameter.

Return type:

b (array)
