Direct conversion receiver is a well-known receiver architecture that enables small, low power and cheap radio. However, I/Q imbalance caused by non-orthogonality between in-phase component and quadrature-phase component from the imperfections of quadrature demodulator is a major problem in this architecture. In addition, carrier frequency offset (CFO) occurs as well. In this paper, we present a register transfer level (RTL) design of joint CFO and I/Q imbalance compensator. We verify that our system can compensate CFO from -500 Hz to 500 Hz when sampling rate is 9.6 kbps under the effect of I/Q imbalance.
