Comparisons of Sparse Channel Estimation in Constant Single-carrier FDMA with valid factor Q

摘要

From the simulation results we can know OMP is able torecovery the channel coefficients both in IFDMA andLFDMA. In Fig.3 and Fig.4, we increase Q to improvebandwidth efficiency and NMSE in LFDMA also increaseabout 7[dB] than IFDMA, since variations of residualbecomes gently and independent columns will be hard toobtain because of mutual coherence in sensing matrix.
