Abstract
A communication system that uses a wired transmission line and multi-carrier modulation includes a transmitting device and a receiving device that are connected through the wired transmission line, wherein the receiving device includes an estimator configured to estimate a first SINR (Signal-to-Interference-Plus-Noise Ratio) of a first sub-carrier and a second SINR of a second sub-carrier, the transmitting device includes a power adjustor configured to boost a transmission power for the first sub-carrier such that an SINR of the first sub-carrier reaches a first SINR threshold corresponding to a first MCS (Modulation and Coding Scheme) that is larger than the first SINR, and back off a transmission power for the second sub-carrier such that an SINR of the second sub-carrier is lowered to a second SINR threshold corresponding to a second MCS that is smaller than the second SINR, and the transmitting device allocates the first MCS to the first sub-carrier.
