Method and device for channel estimation

摘要

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 PI 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 NI is calculated according to the total interfering power PI; 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+NI+N0. 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.

1. A method for channel estimation, comprising:
obtaining a small-scale fading channel of each carrier of each interfering channel respectively according to a Gaussian distribution; calculating a total interfering power PI of all interfering SRSs 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; calculating an interference-equivalent noise NI according to the total interfering power PI; and performing channel estimation according to a Sounding Reference Signal (SRS) Y received by an Evolved Node B (eNB), the SRS Y being taken as the sum of the interference-equivalent noise NI, a product SH, and a channel noise N0, wherein S represents a target SRS transmitted by a target User Equipment (UE), and H represents a target channel carrying the target SRS.
