Document Type and Number:
Japanese Patent JP5808507
Kind Code:
B2
Abstract:
At least one example embodiment discloses a method of determining crosstalk in a multiple-input-multiple output (MIMO) system. The method includes receiving, from at least one first remote node, upstream pilots on an upstream channel, determining upstream channel coefficients based on the received pilots, transmitting, to the at least one first remote node, downstream pilots on a downstream channel, receiving, from the at least one first remote node, loopback pilots on the upstream channel, the loopback pilots being loopback signals of the downstream pilots, and determining downstream channel coefficients based on the received downstream pilots.
