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 for providing said set of code symbols in first and second code symbol subsets having different code symbol rates to first and second modulators, wherein said data rate is equal to a combined said different code symbol rates, said first and second modulators respectively modulating said first and second code symbol subsets according to first and second code symbol rate formats, respectively, wherein said different code symbol rates have a ratio equal a number other than one, to provide modulated first code symbol subset and second code symbol subset; a transmission subsystem for said modulated first code symbol subset on a first carrier frequency and said modulated second code symbol subset on a second carrier frequency.
