Figure 7From: An Adaptive Channel Interpolator Based on Kalman Filter for LTE Uplink in High Doppler Spread EnvironmentsBER performance comparisons of methods for scenario 1. M1: the proposed method which is LS estimate is obtained from the pilots for the CFR used with the Kalman filter and then linear interpolation is used for symbols in between. M2: frequency-domain LS is used. M3: perfect channel state information is used.Back to article page
