Abstract :
An error correction based Doppler estimation method is first proposed to address the Doppler smearing problem in a low signal-to-noise ratio environment with a large Doppler acceleration. This method is shown to effectively increase the detection probability, and a closed-form expression of net error correction probability is also derived.
