摘要：A method for interference mitigation in a wireless communication system having

multiple transmitters and receivers by introducing transmission time delays between thetransmission of signals from the individual transmitters to ensure coherent reception ofthe signals at a specific point in the coverage area, such as at a center of distribution ofthe receivers. To further aid in interference mitigation the signals are assigned trainingpatterns chosen to be distinguishable by the receiver and to optimize interferencemitigation. The training patterns can be selected based on a feedback parameter, e.g., ameasure of the quality of interference mitigation obtained from the receiver. The presentmethod can be used in wireless communication systems which re-use frequenciesincluding TDMA, CDMA, FDMA, OFDMA or other multiplex communication systems usinga multiple access method or a combination of such methods.
