Abstract :
We consider the problem of error localization of complex DFT codes. The problem of error localization of complex DFT codes is analogous to estimating real sinusoids buried in quantization noise. We propose a subspace based algorithm for error localization of complex DFT codes. Simulation results show that the complex DFT code performs better than real DFT code for the case of burst channel errors.
