Webdft-ofdma systems model In this section, the uplink DFT-OFDMA system model is considered with U users, and one base station. DFT is one of the most important models that is used to convert the input signal from discrete-time representation into a discrete-frequency representation in the wireless communication system [ 12 ]. WebIn this paper, we analyze several DFT-based frequency offset estimators for use with the 16-APSK digital modulation scheme. Even a small frequency offset between radio transmitters and receivers can cause phase information to be lost, so a system to align the phases is required to reliably de-modulate PSK signals.
WebFeb 4, 2024 · Assuming that the DFT length is 8192, the performance of proposed algorithm for the five modulation modes listed in Table 2 is shown in Fig. 6. It is clear to be seen the acquisition thresholds of the five modulation modes are different under the Hamming window function, which is summarized in Table 3 .
