Transmitter and Receiver

摘要

A multicarrier transmitter has a first mode, in which the transmitter is configured to transmit a first component carrier signal modulated onto a first carrier by using a first LO signal, and a second mode, in which the transmitter is configured to transmit the first component carrier signal modulated onto the first carrier and a second component carrier signal modulated onto a second carrier by using a second LO signal. The multicarrier transmitter is coupled to a controllable oscillator and configured to adapt a frequency of an LO signal output by the controllable oscillator dependent on the multicarrier transmitter being activated in the first or second mode to output the first LO signal or the second LO signal. For example, the multicarrier transmitter may be configured to switch between the first mode and the second mode while transmitting the component carrier signals.

1. A multicarrier transmitter having a first mode, in which the transmitter is configured to transmit a first component carrier signal modulated onto a first carrier by using a first local oscillator (LO) signal, and a second mode, in which the transmitter is configured to transmit the first component carrier signal modulated onto the first carrier and a second component carrier signal modulated onto a second, different carrier by using a second LO signal,
wherein the multicarrier transmitter is coupled to a controllable oscillator and configured to adapt a frequency of an LO signal output by the controllable oscillator dependent on the multicarrier transmitter being activated in the first mode or the second mode to output the first LO signal or the second LO signal.
