複数の搬送波システムでデータを送信するための方法および装置

Document Type and Number:

Japanese Patent JP4285901

Kind Code:

B2

Abstract:

A wireless transmitter comprising an encoder for encoding a set of information bits to provide a set of code symbols at a data rate. A demultiplexer provides the set of code symbols in first and second code symbol subsets, each having different code symbol rates, to first and second modulators, wherein the data rate is equal to a combination of the different code symbol rates. The first and second modulators respectively modulate the first and second code symbol subsets according to first and second code symbol rate formats, respectively, wherein the different code symbol rates have a ratio equal to a number other than one, to provide a modulated first code symbol subset and a second code symbol subset. A transmission subsystem provides the modulated first code symbol subset on a first carrier frequency and the modulated second code symbol subset on a second carrier frequency.
