DYNAMIC LOW-IF FREQUENCY CONVERSION FOR INTERFERENCE MITIGATION IN A HETERODYNE RECEIVER |
摘要 |
<p>A method of operating a receiver in a communications system is disclosed. The receiver receives a radio-frequency (RF) data signal and converts the RF data signal to an intermediate frequency. The receiver then determines whether a blocker image interferes with the received data signal, and selectively adjusts the intermediate frequency to which the data signal is converted based on the determination. The receiver may lower the intermediate frequency if the blocker image interferes with the received data signal. The receiver may also deactivate a quadrature chain of the receiver if the blocker image interferes with the received data signal.</p> |
