A Matlab wrapper file for generating 11ah channel profiles using this implementation is provided in the Appendix. This channel model shall be used to evaluate 11ah outdoor link and system performance for SISO or MIMO links. TGah use cases involve up to pedestrian mobility. However as reported in [4] and [5], reflections from cars cause higher Doppler and can be represented by assigning one of the six channel paths a higher Doppler value. The following two simulation scenarios shall be used: SCM with speed up to 3kmph for all paths SCM with the fourth path assigned a speed of 60kmph and the rest of the paths assigned 0kmph.
