There is provided a channel equalization device. The channel equalization device comprises a receiver configured to receive a plurality of consecutive reception symbol sequences through multiple channels; a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory, wherein the instructions, when executed by the processor, cause the processor to estimate a transmission symbol at a position of interest among a plurality of consecutive transmission symbol sequences based on the plurality of received reception symbol sequences using a neural filter trained by training reception symbol sequences.

Channel equalization device and method, and computer readable storage medium storing instructions to perform channel equalization method

A communication method of a heterogeneous distributed wireless network system includes calculating a first transmission threshold in the heterogeneous distributed wireless network system including a plurality of distributed networks that share a same frequency band, determining whether data is transmitted by transmitter/receiver pairs included in the heterogeneous distributed wireless network system, based on the first transmission threshold, calculating a second transmission threshold locally for each of the distributed networks, based on whether data is transmitted by at least one transmitter belonging to the transmitter/receiver pairs, selectively determining whether data is transmitted for each of the distributed networks based on the second transmission threshold, and transmitting the data.
