Abstract
Methods, systems, and devices are described for wireless communication at a wireless communication device. A wireless communication device may receive a data frame and use it to estimate a residual channel length (RCL). The device may then modify a finite impulse response (FIR) filter based on the estimated RCL. For example, the device may add additional taps to the FIR filter. The device may continue to adjust the FIR filter until the RCL is at or near zero. In some cases, the wireless communication device may send an indication to the transmitting device to adjust an FIR filter based on the estimated RCL. In some cases, the length of a guard interval may also be adjusted based on the estimated RCL.
