tau and pdb in IEEE 802.11n channel model

I am trying to model the effect of the channel to the input signal. Say the input signal is inputSig and the channel impulse response is h, we get y = step(h, inputSig)

I want to use the IEEE 802.11n channel model in Matlab. here is the link: http://www.mathworks.co.uk/help/comm/examples/ieee-802-11n-channel-models.html#chandemo_802_11n-10

The problem is, this channel model is based on the Saleh-Valenzuela (S-V) Channel Model. And according to the document published by IEEE (IEEE P802.11 Wireless LANs, "TGn Channel Models", IEEE 802.11-03/940r4, 2004-05-10.), the tap is not distributed continuously, e.g., for channel model C in the document, tau=[0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 110, 140, 170, 200].

So when we model it in the Matlab, what should we do to the tau and the corresponding pdb?
