The embodiment of the invention discloses an interference power control method of a distributed wireless network, a transmitter and a receiver. The interference power control method comprises the following steps that: a transmitting node monitors reverse interference link power control information transmitted on a sub-frequency band by a signal receiving node, wherein the reverse interference link power control information is determined by the signal receiving node according to tolerable maximum interference power and a correlation sequence selected in a correlation sequence group; the transmitting node calculates correlation peak according to the monitored reverse interference link power control information and the correlation sequence group; and the transmitting node determines maximum transmission power on the sub-frequency band according to the peak value of the correlation peak. With the interference power control method of the distributed wireless network adopted, maximum transmit power of communication nodes can be obtained more accurately, and communication quality can be better ensured.
