  Abstract/
Summary
Wireless communication channels are time variant due to the mobility of receiver. However, existing subspace-based methods for ZP-OFDM system are not capable of tracking even slow channel variations. In this paper, to cope with the blind channel tracking problem for zero padding OFDM (ZP-OFDM) system, a neural network based on projection approximation subspace tracking (PAST) is developed. Simulation results illustrate that the proposed method provides satisfactory tracking performance.
