We present a framework for joint estimation and compensation of three major oscillator impairments, namely sampling time error (STE), carrier frequency offset (CFO) phase noise (PN). In particular, we model these impairments as Wiener processes introduce pilot-aided approach which facilitates their estimation. The proposed solution is carried out in two steps: first, an initial the transmitted symbols acquired by applying extended Kalman filter (EKF) on pilot then, second EKF applied...
This paper analyzes the achievable rate of single-carrier system with a frequency-domain equalizer (SC-FDE) under receiver in-phase/quadrature phase (I/Q) imbalance in radio frequency front-end. We consider linear schemes based on minimum mean square error (MMSE), zero-forcing equalization, and matched filter. derive SC-FDE hit by I/Q for mentioned scenarios. show that depending value parameters, approaches saturation level. To examine validity our analysis, we compare it simulation results...
In this paper, we propose a real-valued multi-input memory polynomial (MP) for behavioral modeling of mixer, which considers nonlinearity introduced by in-phase, quadrature and the local oscillator (LO) inputs. By splitting I Q data stimulus LO signal, use 4-input 2-output structure MP model. The experimental validation based on measured from real mixer confirms effectiveness our proposed Compared with Volterra series in literature, has similar accuracy much lower complexity,
