Polarization sensitive arrays can suppress the interferences by taking advantage of differences in polarization domain while the interferences and desired signals are from the same direction. In this paper, a 4-element dual-linear-polarized array is used to realize the anti-jamming function in joint spatial-time-polarization domain. A Right-Hand Circular(More)
Regression is one of the important problems in statistical learning theory. This paper proves the global convergence of the piecewise regression algorithm based on deterministic annealing and continuity of global minimum of free energy w.r.t temperature, and derives a new simplified formula to compute the initial critical temperature. A new enhanced(More)
An iterative least-squares (RLS) anti-jamming technique is applied to a conformal antenna for improving the adaptive anti-jamming performance. This method offers a solution to synthesize predefined radiation pattern. By iterative calculation, a set of constraint weights of linearly constrained minimum variance (LCMV) can be obtained to improve the adaptive(More)
Multichannel wavelength converters may be important components in the cross connects in future wavelength division multiplexing (WDM) optical network. We first present simulations of a scheme to perform dual-wavelength conversion of 16QAM signals based on four wave mixing (FWM) in semiconductor optical amplifier (SOA) without pump phase noise.
