Problem with implementing WiMAX interleaving permutations

[tplay]

In 802.16e OFDMA PHY, following two interleaving permutations should be implemented in Simulink model.

mk =(Ncbps ⁄ d)⋅ kmod(d) + floor(k ⁄ d)
jk =s floor (mk⁄ s)+(mk + Ncbps – floor(d ⋅ mk ⁄ Ncbps))mod(s)
where k = 0, 1, …, Ncbps – 1 and d = 16

In my case, I am running a DL PUSC in 1024 FFT size with 16QAM 3/4
Ncbps=encoded block size = 1440
Ncpc =number of coded bits per subcarrier. (for 16QAM Ncpc=4)
S=Ncpc/2= 2

Thus, I set these two step permutations as following:
mk= (1440/16) . mod([0:1439],16)+ floor ([0:1439]/16)
jk= 2 floor (mk / 2)+ (mk + 1440- floor(16 * mk / 1440)) mod (2)

I was wondering anything wrong with that?
coz Simulink pop up a wrong message "commblkinterl Invalid Elements specified."
anyone can help me to solve that? thanks !

wimax interleaving

Respected sir,
I am viswanathan.R doing Master of Engineering in wireless.I need the code for fft and ifft to implement my final project.Please sent me the code as soon as possible.Interestingly waiting for your mail.
