SDR4Teaching >> RF impairments

Estimation of the RF impairments of the USRP throught channel impulse response estimation Tutorial to estimate the channel impulse response of the channel between two USRP (universal software radio peripheral). This tutorial also informs about the RF impairments of the USRP Frequency offset estimation with linearly modulated sequence of symbols Estimation of the frequency offset of the received signal with two methods. The first one is based on the autocorrelation function of the received signal and the second on training sequences
