Abstract
A communication system periodically changes the carrier wave frequency or phase such that a signal traveling a reflected path no longer destructively interferes with a signal traveling a direct line-of-sight path. The communication system negotiates a periodic frequency or phase shift with a receiver, and then shifts the frequency or phase according to the negotiated schedule to maintain continuous communication.
