Title:
DEVICE AND METHOD FOR CHANNEL ESTIMATION USING SHORT/LONG-TERM MEMORY NETWORK IN MILLIMETER-WAVE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/027329
Kind Code:
A1
Abstract:
A device and a method for channel estimation using a short/long-term memory network in a mmWave communication system are disclosed. The disclosed channel estimation method comprises the operations of: inputting a received pilot signal of a time slot to a short/long-term memory network; estimating a channel change state by using, as an input, the received pilot signal of the time slot in the short/long-term memory network so as to extract a time-varying channel feature embedding vector; estimating a parameter of a channel model by using, as an input, the time-varying channel feature embedding vector in a fully connected network; and estimating a channel for the received pilot signal of the time slot by using the parameter of the channel model.
