Abstract: A constant K-user interference channel in which the users are notsymbol-synchronous is considered. It is shown that the asynchronism among theusers facilitates aligning interfering signals at each receiver node while itdoes not affect the total number of degrees of freedom (DoF) of the channel. Toachieve the total K/2 DoF of the channel when single an..
