Abstract:
A method for extending transmission distance of an ADSL signal includes: increasing power spectral density (PSD) of an ADSL signal when a parameter of the ADSL signal is equal to or greater than a preset threshold; and sending the ADSL signal with the increased PSD. A system for extending transmission distance of ADSL signal includes a PSD adjustment determining unit, a PSD adjusting unit and a transmitting unit. A method for promoting transmission rate of an ADSL signal is disclosed as well. The solution extends the coverage of the ADSL signal, and when the CO increases the downlink PSD, the CEP need not to be modified, which reduces the cost.
