Title:
A TRANSMISSION METHOD AND SYSTEM OF THE DISCRETE MULTI-TONE MODULATION DATA
Document Type and Number:
WIPO Patent Application WO/2007/079686
Kind Code:
A1
Abstract:
A transmission method and system of the discrete multi-tone modulation data,
the method includes: A, the transmitter generates a first bit table based on the
data to be transmitted, and the items of the first bit table include the information
of each line carrying the data when the data is transmitted at that time; B, the
transmitter modulates the data according to the first bit table and transmits
it to the receiver; C, the receiver performs demodulation according to the first
bit table and obtains the corresponding data. The transmission method and system
of the discrete multi-tone modulation data provided in the embodiments of the
invention uses a dynamic bit table to carry the variable information of the line
carrying data, so that the rate and the transmitting power of the lines can be adjusted
according to the information ration of the line transmission dynamically and
in real time, and the line resource and power resource can be saved.
