TRANSCEIVER DEVICE AND A METHOD FOR GENERATING A COMPENSATION SIGNAL

摘要

A transceiver device 100 includes a transmit path module 110, a receive path module 120 and a compensation signal generator module 130. The transmit path module 110 generates a high frequency transmit signal 112 based on a baseband transmit signal. The receive path module 120 generates a baseband receive signal 122 based on a received high frequency receive signal 114. Further, the compensation signal generator module 130 generates a compensation signal 132 comprising at least one signal portion with a frequency equal to a frequency of an undesired signal portion of the baseband receive signal 122 caused by an undesired signal portion within the high frequency transmit signal 112 comprising a frequency equal to an integer multiple larger than 1 of a transmit frequency of the high frequency transmit signal 112.

1. A transceiver device comprising:
transmit path circuitry configured to generate a high frequency transmit signal based on a baseband transmit signal comprising a frequency component; receive path circuitry configured to generate a baseband receive signal based on a received high frequency receive signal; and compensation signal generator circuitry configured to generate a compensation signal by nonlinear signal processing of the baseband transmit signal, the compensation signal comprises at least a signal portion of a harmonic of the frequency component that interferes with a channel bandwidth of the receive path circuitry.
