A reconfigurable IF receiver supporting intra-band non-contiguous carrier aggregation is proposed. By utilizing the harmonic rejection (HR) mixer with 12-phase LOs and phase-shift-adding configuration, the IF receiver could eliminate the channel interferences, which is robust to the mismatch. The IF receiver has been implemented in 65nm CMOS, and the simulate d results show that the interference between...
For ship course control system, this paper proposes a class of sliding mode variable structure control method (SMVSC) based on RBF neural network. The mathematical model of ship steering system possesses parametric perturbation and external disturbances, which combines the advantages of RBF neural network and sliding mode control. The controller is given by the output of RBF neural network and the...
How to improve the performance of Global Navigation Satellite System (GNSS) receiver in purposive interferences and complex electromagnetic environment is a challenge topic. Moreover, the small angle offset in interference direction, which is caused by high-speed relative motion between jammer and receiver makes big trouble for anti-jammering processing. Although some null broadening technics have...
