Adaptive harmonic rejection receiving device and method

Abstract

The invention provides an adaptive harmonic rejection (HR) receiving device, including a low noise amplification module; at least one HR mixer; at least one non-harmonic rejection (NHR) frequency mixer; and a control device. A received signal passes through the low noise amplification, and then passes through the at least one HR mixer or the at least one NHR mixer; the control device measures a receiving signal strength index (RSSI) after the received signal passes through the at least one HR mixer or the NHR mixer, and selects an NHR mixer or an appropriate HR mixer for the received signal according to a result of the measurement. The adaptive HR receiving device of the present invention is capable of adaptively judging whether to implement HR or determining which HR to implement according to features of the received signal, thereby improving the reception flexibility and reception performance.
