Abstract / Description of output

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 a wireless receiver that carefully exploits Doppler effect for cochannel interference mitigation. The proposed system-termed as DAIM to stand for Doppler Assisted Interference Mitigation-exploits the propagation environment and the network topology, and consists of an access point with a rotating 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 a simulation study. The results show that under favorable fading conditions, co-channel interference can be significantly reduced if not eliminated. Therefore, it is anticipated that more sophisticated wireless systems and networks can be designed by extending the basic system proposed herein.
