METHOD AND SYSTEM FOR ESTIMATING A TRANSMISSION CHANNEL OF A COMMUNICATION LINK

The invention relates to a system (10) and a method for estimating a transmission channel of a communication link (11). A transmitter (20) is configured to transmit a first transmission signal (11a) and a receiver (30) is configured to receive the first transmission signal (11a) through the transmission channel. The first transmission signal (11a) includes a plurality of data elements and a plurality of pilots, each of the plurality of pilots being located at specified locations within a time-frequency domain (13) of the first transmission signal (11a). The receiver (30) is configured to determine a level of interference for each of the plurality of pilots, the level of interference being indicative of an extent of distortion on a respective pilot caused by a second transmission signal (11b) interfering with the first transmission signal (11a). The receiver (30) is further configured to determine an interference-mitigated pilot for each pilot based on the determined level of interference determined for each respective pilot. The receiver (30) is further configured to use the determined interference-mitigated pilots to estimate the transmission channel of the first transmission signal (11a).
