Abstract
This dataset is about channel state information about underwater channels, we adopt the widely-used UWA channel simulator developed by P. Qarabaqi and M. Stojanovic to make this dataset. Addtionlly, the parameters settings of UWA-Channel are as follows: the depth of sea is 100 meters, the transmitter is positioned 50 meters above the sea bottom, the height of the receiver from the bottom is 30 meters, and the distance between the two is 800 meters. The dataset consists of two parts: data and labels. Labels are the channel frequency responses generated by the simulator. Data are the received symbols in multi-carrier communication system, which is known in pilot positons.
The number of subcarriers is 128, each frame is composed of 10 symbols, the size of a CSI matrix is 128*10. We select the 3th symbol and 7th as pilots and adpot the least square algorithm to compute the channel frequency response of pilots. The dataset has a size of 20000, with each data and label corresponding to each other in sequential order.
