Delay and Doppler estimation using cyclostationarity based cross correlation in a multipath environment

Cyclostationarity based cross correlation delay estimation is known for its substantial tolerance to noise and interference. The multipath echoes of a transmitted signal presented at the receiver, which are not similar to noise and interference, hamper the delay and Doppler estimation from the reflection of the moving target. Thus, suppression of the multipath signals is necessary. In this paper, a cyclostationarity based multipath suppression technique is presented. An example is illustrated to demonstrate its advantage.
