Multi-dimensional carrier sensing method and apparatus and receiving end device

Provided are a multi-dimensional carrier sensing method and apparatus and a receiving end device. The multi-dimensional carrier sensing method of the present invention comprises: a receiving end device receiving signals sent by two or more network devices, wherein the two or more network devices comprise a sending end device and at least one adjacent device; and by means of maximizing the signal-to-noise ratio of a channel between the sending end device and the receiving end device, the receiving end device acquiring an optimal signal correction vector, and processing the signals via the optimal signal correction vector so as to eliminate the signal interference from the at least one adjacent device. The embodiments of the present invention solve the problem in the prior art of all the received signals being processed into very small ones, even zero, which results in a device being unable to receive and send a signal normally, and may also reduce the signal transmission rate, thus reducing the throughput of a cell.
