Abstract:
1. A transmitter stage configured to transmit modulation symbols on multiple component carriers, comprising: a first Discrete Fourier Transform (DFT) coder operable to receive modulation symbols to be transmitted on at least one component carrier; a first Orthogonal Frequency Division Multiplexing (OFDM) modulator associated with said first DFT coder, said first OFDM modulator coupled to said first DFT coder to receive output from said first DFT coder; a first power amplifier coupled to receive output of said first OFDM modulator and operable to amplify said output for transmission on the at least one component carrier; a second DFT coder operable to receive modulation symbols to be transmitted on a set of component carriers, wherein the component carriers of the set of component carriers are non-contiguous relative to each other and are distinct from the at least one component carrier; a second OFDM modulator associated with said second DFT coder, said second OFDM modulator coupled to said second DFT coder to receive output from said second DFT coder; and a second power amplifier coupled to receive output of said second OFDM modulator and operable to amplify said output for transmission on said set of component carriers.
