As shown in Figure 15-4, the receiver can be described using a mathematical formula: Y1 = H11*X1 + H12*X2 + ... + H1n*Xn. That is, X1 can be received by Y1, Y2, and ... Yn. To obtain the transmit signal, the receive end needs to solve the equation. Figure 15-4 Mathemati...
The SNR is calculated using the following formula: , where: SNR: signal-to-noise ratio, in dB PS: effective power of signals PN: effective power of noise signals SINR The signal to interference plus noise ratio (SINR) is the ratio of the strength of signals to the total strength of inte...
