Embodiment Construction
[0152] The channel estimation and channel identification method in the intelligent reflective surface communication system proposed by the present invention, its flow chart is as follows figure 2 shown, including the following steps:
[0153] (1) Set a base station in the communication system, the base station has M antennas, a user, the user has an antenna, and an intelligent reflector with two intelligent reflective elements, the mixed signal received by the base station includes: user The signal sent, the signal sent by the user is reflected by the first intelligent transmitting element, and the signal sent by the user is reflected by the second intelligent reflecting element. The process of receiving the mixed signal by the base station includes the following steps:
[0154] (1-1) At the tth moment when the user sends the signal, the mixed signal received by the base station is:
[0155]
[0156] Among them, 1≤t≤T, T is the length of the data signal sent by the user t...
