Channel estimation using a sliding window technique |
摘要 |
<p>The invention provides a method for channel estimation in mobile radio communications which adaptively compensates for channel distortion on a block-by-block basis. The discrete-time channel impulse response is initially estimated with a given length and then truncated by using a sliding window. A cost function associated with the window is measured as the length and position of the window is adjusted over the channel impulse response and the cost function is compared with a threshold. The invention provides means to and a method for adaptively adjusting the length of the window LT and the corresponding number of states in the equalizer, 2<L>T - 1 if appropriate.</p> |
