Channel estimation method and device of SIMO system and storage medium

The invention discloses a channel estimation method of an SIMO system. The method comprises the following steps: acquiring a data frame sent by a sending end of the SIMO system; according to the data received by each receiving antenna of the receiving end of the SIMO system, calculating to obtain a channel proportional relation of a plurality of receiving antennas of the receiving end; acquiring a data signal which is received by the receiving end and corresponds to the training sequence; and optimizing the channel proportional relation and a data signal which is received by a receiving end and corresponds to the training sequence according to a set optimization criterion to obtain an optimization result, and obtaining channel estimation of each receiving antenna of the receiving end according to the optimization result. Compared with the prior art that channel estimation is realized only through a training sequence, the accuracy of channel estimation can be greatly improved. The invention further discloses a
