Co-Channel Dual Polarization (CCDP) technology is an efficient way to double the link capacity in modern communication system. However, the consequent polarization interferences become an inevitable problem to fight. Therefore, a Cross-Polarization Interference Canceller (XPIC) is necessary against the cross-talks. This paper focuses on the baseband XPIC technology and builds a simulink model to show...
We investigate the parameter estimation problem of polynomial phase signals with time-varying amplitudes. For many models of polynomial phase signals with time-varying amplitudes, the parameters can be expressed by the coefficients of its finite-order Taylor series expansion. And the estimation of phase and amplitude parameters can be converted to the estimation of the Taylor coefficients. We propose...
