title = "Digital self-healing using smart sensing technique for IQ mismatch and lo leakage against non-flat path response in mmwave communication system",
abstract = "In this paper, we propose a self-healing technique with the smart sensing capability to exactly estimate and pre-compensate both the imperfect effects of IQ mismatch and LO leakage of the up-conversion mixer under the non-flat path impulse response (PIR) for improving TX EVM in 60 GHz broadband wireless communication systems. The proposed method may use the direct digital frequency synthesis (DDFS) module to send the test signals including a single-tone (ST) and a two-tone (TT) modes for sensing PIR and estimating the imperfect effects of the up-conversion mixer, respectively. The 8-bit fixed-point simulation result shows the proposed technique can achieve very excellent results.",
