WebSep 25, 2024 · The BER as a function of SNR (Eb/No) for the two systems in Figs. 2 and 3 is plotted as shown in Fig. 4. It is found that the output of the BER with Rayleigh fading is the lowest relative to that of the AWGN channel alone. Therefore, the fading model of the Rayleigh performs better where there is a clear line of sight signal.
WebMar 15, 2024 · The main disadvantage of the electromagnetic acoustic transducer (EMAT) is low energy-conversion efficiency and low signal-to-noise ratio (SNR). This problem can be improved by pulse compression technology in the time domain. In this paper, a new coil structure with unequal spacing was proposed for a Rayleigh wave EMAT (RW-EMAT) to … WebFeb 15, 2024 · We propose a DNN model such that it can utilize the channel information, such as a Rayleigh multipath fading channel. When the system uses K orthogonal resources, the total number of channel coefficients is K , for instance, four channel coefficients can be utilized in six by four DSM systems.As depicted in Figure 9 , the number of input nodes is …
WebSep 26, 2013 · Simulation results show that the BER performance of the practical coherent receiver is close to the ideal coherent receiver, for data length equal to the preamble length, and attains a BER of about 4× 10^{-5} at an SNR of just 8 dB. It is also shown that the probability of erasure is less than 10-6 for a preamble length of 512 QPSK symbols.
