<p>The disclosure provides a method for channel estimation, including that: a small-scale fading channel of each carrier of each interfering channel is obtained respectively according to a Gaussian distribution; a total interfering power P I of all interfering SRSs is calculated according to the obtained small-scale fading channel of each carrier of each interfering channel and a generated large-scale fading gain of each carrier of each interfering channel; interference-equivalent noise N I is calculated according to the total interfering power P I ; and channel estimation is performed according to a Sounding Reference Signal (SRS) Y received by an Evolved Node B (eNB), wherein Y is calculated with a formula Y =SH+N I +N 0 . The disclosure further provides a device for channel estimation. With the disclosure, it is not required to generate small-scale fading of an interfering channel, reducing complexity of, and thereby improving efficiency in, simulation.</p> |
