METHOD OF ESTIMATING SIGNAL-TO-NOISE RATIO AND ADJUSTING FEEDBACK INFORMATION TRANSMISSION |
摘要 |
A method of estimating a signal-to-noise ratio by considering user mobility, a method of adjusting feedback information transmission, an adaptive modulation and coding method using the same, and a transceiver thereof are disclosed. The present invention includes measuring a first channel parameter and a second channel parameter using first and second symbols sequentially received, respectively, estimating a channel quality considering a time delay between measurements of the first and second channel parameters using the first and second channel parameters, and transmitting information for the estimated channel quality if a variation of the first and second channel parameters is equal to or greater than a prescribed threshold. Accordingly, the present invention reduces performance degradation and feedback overhead caused by a time delay in channel quality estimation. |
