ML estimation of time and frequency offset in OFDM systems

OFDM系统仿真涵盖频偏估计的matlab代码，测试运行成功-OFDM system simulation covers the frequency offset estimation matlab code, test runs successfully

This model shows the implementation of a QPSK transmitter and receiver. The receiver addresses practical issues in wireless communications, e.g. carrier frequency and phase offset, timing offset and frame synchronization. The receiver demodulates the
