Performance Analysis of NOMA in Drone Communication

UAV-Assisted NOMA-Based Network with Alamouti Space-Time Block Coding

“…For the sake of simplicity 1 2 = 2 2 = 2 is used in this form. For the network that uses 2x1-MISO A-STBC and NOMA techniques together in the system by extracting the antenna indexes, the equivalent noisy single input single output signal expression in the 'th user is shown in (6).…”

“…The expressions ‖. ‖ and ̃ in (6) show the Frobenius norm of the matrix and equivalent complex additive gaussian noise, respectively. Here ̃ has distribution as ̃~(0, ‖ℎ ‖ 2 2 ) [19].…”

“…For the sake of simplicity, it is assumed that all of them have the same mean and variance. The equivalent single input and single output signal expression of (7) can be written as in (6). As the channel matrix changes in (7), the PDF of the SNR in the receiver and the variance of Gaussian noise will also be changed in the system.…”
