Zusammenfassung:Channel estimation is a crucially important part of the OFDM technology to maintain the performance. One of channel estimation technique is 2-D channel estimation which using time and frequency domain together. Conventional channel estimation has improved performance but has a weakness of too much pilot usage. Therefore, in this paper suggest that the 2-D channel estimation which has reduced number of pilot using WSSUS channel characteristic.
