CHANNEL ESTIMATION METHOD AND APPARATUS

摘要

The present invention relates to the field of communication, and discloses a channel estimation method and apparatus. The present invention resolves the problem that amount of data stored in a chip is very large in the prior art. The apparatus includes: a matrix storage unit (101) for storing intermediate inverse matrices; a matrix acquirement unit (102) for acquiring inverse submatrices corresponding to numbers of training sequences of two users from the intermediate inverse matrices stored in the matrix storage unit; a logic calculation unit (103) for implementing multiplication and addition logical operation to the inverse submatrices acquired by the matrix acquirement unit and matrices generated from the training sequences corresponding to the numbers of the training sequences of the two users, and acquiring channel estimation factors; a channel estimation unit (104) for completing channel estimation process according to the channel estimation factors calculated by the logic calculation unit.
