|Method and transceiver for cancelling multi-carrier transmission interference|
A method, an apparatus, and a transceiver for cancelling multi-carrier transmission interference are provided. The method includes: collecting a high order intermodulation signal in radio frequency signals output by a transmitter; processing the high order intermodulation signal so as to generate a first digital signal; establishing a high order intermodulation model by using the first digital signal and a first baseband signal output by the transmitter; generating a second digital signal by using a coefficient of the high order intermodulation model and a second baseband signal output by the transmitter; and counteracting interference in a digital signal output by a receiver with the second digital signal.
|Communication scheme for channel quality information|
The invention relates to a method for receiving and a method for reconstructing channel quality information in a communication system. Further, the invention also provides a transmitter and receiver performing these methods, respectively.
|Systems and methods for high rate ofdm communications|
Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters.
