Abstract
A system and a method for estimating a transmission channel of a communication link. A transmitter can transmit a first transmission signal and a receiver can receive the first transmission signal through the transmission channel. The first transmission signal includes data elements and pilots, each of the pilots being located at specified locations within a time-frequency domain of the first transmission signal. The receiver can determine a level of interference for each of the pilots, the level of interference being indicative of an extent of distortion on a respective pilot caused by a second transmission signal interfering with the first transmission signal. The receiver can further determine an interference-mitigated pilot for each pilot based on the determined level of interference determined for each respective pilot. The receiver can use the determined interference-mitigated pilots to estimate the transmission channel of the first transmission signal.
