ABSTRACT:
A system and a method for receiving and processing broad-band signals in a software defined radio (SDR) terminal are provided. The system comprises first and second frequency pass units and an analog to digital signal converter (A/D converter). The first frequency pass unit converts an analog radio frequency (RF) signal into a direct current (DC) level signals and removes noise and DC components from the analog RF signal, if the RF signal is a high frequency signal. Otherwise, the second frequency pass unit removes noise and DC components from the analog RF signal, if the RF signal is a low frequency signal. The A/D converter converts the RF signal into a digital RF signal after the DC components are removed.
