Title: RADIO FREQUENCY (RF) TRANSMITTER AND NOISE MITIGATION DEVICE
Abstract:
A radio frequency transmitter for wireless communication includes a plurality of input ports to receive a plurality of sequences of baseband symbols to be transmitted on a plurality of disjoint frequency bands, a power encoder to modulate and encode the plurality of sequences of baseband symbols to produce an encoded multi-band signal including the plurality of disjoint frequency bands carrying the plurality of sequences of baseband symbols, a first power amplifier for amplifying the encoded multi-band signal to produce an amplified encoded multi-band signal, a first noise canceller to generate a first noise mitigation signal from the encoded multi-band signal and the plurality of sequences of baseband symbols, a first power combiner to combine the amplified encoded multi-band signal and the first noise mitigation signal to produce an RF multi-band signal, and an antenna for transmitting the RF multi-band signal.
