This paper focuses on stability analysis and stabilization of a switched system under average dwell time criteria in the continuous-time domain.The matrix polynomial approach is applied to the switched system to construct a continuous Lyapunov function and design a more effective controller, which can not only improve the system performance but als
Direct-conversion architecture-based orthogonal frequency division multiplexing (OFDM) systems are troubled by impairments such as in-phase and quadrature-phase (I/Q) imbalance and copyright frequency offset (CFO).These impairments are unavoidable in any practical implementation and severely degrade the obtainable link performance.In this contribut
