Taean and Incheon Measured Data

The analysis is based on two kinds of measured dataset. In both cases, uplink data are measured (A-UL0) i.e. the transmitters are UBSs and the receiver is UBSC and FDD is used. The first dataset has been collected from August 17, 2018, to August 20, 2018. The experiment has been carried over two separate distances, i.e., 1 km, and 3 km between the transmitter (Tx) and receiver (Rx) in Mohang Port (Taean-gun).  

The latitude and longitude coordinates for 1 km and 3 km distances were: Tx—36°54'43.13''N 126°12'21.53''E and Rx—36°54'11.83''N 126°11'27.90''E, and Tx—36°54'44.43''N 126°12'37.33''E and Rx—36°54'05.40''N 126°11'18.83''E, respectively. The second is from a 24-hour experiment from July 5, 2017, to July 6, 2017. The experiment has been carried out over a 2 km distance between the Tx and Rx in the Yellow Sea (Deokjeokdo, Incheon). The latitude and longitude coordinates were Tx—

37°13'28.2"N 126°12'12.0"E and Rx—37°14'22.7"N 126°12'55.1"E.

There was a total of 288 combinations of different kinds of parameters, and 417 sets of experimental data in the Taean dataset[16], which is a good reason to take a step-by-step approach in selecting the suitable modulation and coding scheme (MCS) levels. The process to analyze the Taean dataset has been divided into three stages, which included three-dimensional analysis, modulation-wise analysis, and a fixed SNR strategy. Unlike the Taean dataset, the Incheon dataset has 108 combinations of parameters and 10,105 sets of experimental data. This enormous dataset makes it impossible to analyze with any kind of strategy other than the ML approach.
