Interleaving

In the interleaving stage, codewords are interleaved so that in the end the change of burst bit errors is reduced.

This can be easily implemented by for example a simple python for loop, where D is the original matrix and I is the interleaved matrix. Sf is the spreading factor and cr is the coding rate.

    for i in range(0, cr):
        for j in range(0, sf):
            k = np.mod((i - j - 1), sf)
            I[i][j] = D[k][i]
