METHOD, EQUIPMENT AND SYSTEM FOR CHANNEL ESTIMATION |
摘要 |
<p>In the field of communications technologies, a method, an apparatus, and a system for channel estimation are provided. The method for channel estimation includes the following steps. An error signal returned by a terminal is received, where the error signal is an error signal of at least two tones in a downlink frequency band. Channels of the at least two tones are obtained according to the error signal. The channels of the at least two tones are interpolated, and channels of remaining tones in the downlink frequency band are obtained. In the method, the apparatus, and the system for channel estimation, a convergence speed of the channel estimation is improved by reducing data of error signals returned by the terminal.</p> |
