Abstract
Various embodiments are described that relate to signal distortion for delay and attenuation. A transmission antenna can transmit a baseline signal to a reception antenna and then transmit a test signal to the reception antenna. The baseline signal and test signal can be processed to determine undesirable attenuation and delay coefficients. These coefficients can be transmitted back from the reception antenna to the transmission antenna. Based on these coefficients, a determination can be made on how to modify a signal of interest such that the signal of interest arrives from the transmission antenna to the reception antenna absent the undesirable attenuation and delay coefficients. The transmission antenna can transmit the modified signal of interest such that it arrives at the reception antenna absent the undesirable delay and attenuation coefficients.
