METHOD AND DEVICE FOR CHANNEL ESTIMATION WITH COLLIDING INTERFERENCE CANCELLATION

摘要

PROBLEM TO BE SOLVED: To provide a method and device for channel estimation with colliding interference cancellation.SOLUTION: The method comprises: a receiving step of receiving a signal including a symbol-carrier matrix, the symbol-carrier matrix including a predetermined pattern of reference symbols, the reference symbols including a target reference symbol; a step of determining a first channel estimate vector on the basis of demodulating received reference symbols with known reference symbols; and a step of determining a second channel estimate vector by multiplying the first channel estimate vector by an interference cancellation matrix. The second channel estimate vector includes an interference cancelled channel estimation at a position of the target reference symbol.
