This paper proposes an iterative demodulation method applied in the bit-Interleaved QPSK system.

By means of the method of upper and lower solutions and monotone iterative technique, the existence of maximal and minimal solutions of the paratrized boundary value problems for first order impulsive differential equations are established under the assumption that correponding functions satisfy the onesided Lipschitz condition.

An iterative solution of AXB=C with sub-matrix restrains in bi-symmetric matrix set is given.

In this paper, the iterative solution of the three dimensional ageostrophic circulation di-agnostic equation is discussed.

Inversion of scattering from a layer of non-spherical particles using iterative solutions of the scalar radiative transfer equation;

In this paper, the iterative solution is studied for the equation x+Tx=f with a k-subaccretive operator T in a uniformly smooth Banach spaces, where T is neither necessarily accretive nor Lipschitzian.

In this paper we discuss conjugate direction method for LS estimator and analyse error of iterative solution.

Based on the analysis of the constellation mapping in bit interleaved coded modulation and iterative decoding(BICM-ID),design rules are proposed in iterative demodulation and decoding.

The new codes perform well using the sum-product algorithm for iterative decoding.
