STAR-RIS_CE

A hybrid-field STAR-RIS dataset. we have provided the paired samples for hybrid-field cascaded channel estimation in STAR-RIS systems, in which the data preprocessing and normalization operations have been completed.

The simulation parameters of this dataset have been elaborated in our submitted paper. For instance, M_1 x M_2 = 4 x 8, N_1 x N_2 = 4 x 32, f_c = 28GHz, and Q=N/4.  The  description of each data file is listed as follows.

inHmix_28_32_128_K2_32pilot.mat: the training dataset and validation dataset in the ES protocol.<br/>

inHmix_28_32_128_test_K2_32pilot.mat: the testing dataset in the ES protocol.<br/>

inHmix_28_32_128_S_32pilot.mat: the training dataset and validation dataset in the TS protocol.<br/>

inHmix_28_32_128_test_S_32pilot.mat: the testing dataset in the TS protocol. The dataset in the TS protocol is packed a Zip file due to the limitation of the uploading space.
