This paper proposes a noise-reduction method to improve the channel-estimation performance in digital video broadcasting-terrestrial (DVB-T) receivers. In DVB-T receivers, channel estimation is usually carried out in frequency domain using known symbols, referred to the pilot. A least-squares (LS) estimator has been preferred for channel estimation due to the low complexity but it may be vulnerable to noise because it does not consider noise effect in obtaining its solution. To compensate for… CONTINUE READING
