  Doppler effect is a fundamental phenomenon that appears in wave propagation,
where a moving observer experiences dilation or contraction of wavelength of a
wave. It also appears in radio frequency (RF) wireless communication when there
exists a relative movement between the transmitter and the receiver, and is
widely considered as a major impairment for reliable wireless communication.
The current paper proposes Doppler Assisted Wireless Communication that
exploits Doppler effect for co-channel interference mitigation. The proposed
system also exploits the propagation environment and the network topology, and
consists of an access point with a rotating thin drum antenna. The rotating
drum receive antenna is designed in such a way that it shifts the interference
signals away from the desired signal band. This paper includes a detailed
system model, and the results show that under favourable fading conditions,
co-channel interference can be significantly reduced. Therefore, it is
anticipated that more sophisticated wireless systems and networks can be
designed by extending the basic system proposed herein.
