Based on the geometrical meaning of structural reliability index, the direct iteration calculation of a nonlinear function under the condition of correlated variables was discussed by using coordinate transformation and matrix operation.

In this iterative receiver,a minimum mean square error(MMSE) filter was applied only in the first iteration,and matched filter was utilized in the second and later iterations to reduce computational complexity.

Based on the interval iterative computations of the linear constrained function,the region bisection method and region deletion testing rules,a interval algorithm is established.

An iterative receiver combining multiple-input multiple-output(MIMO) detection and channel decoding was proposed for coded group-wise space-time block coding(G-STBC) MIMO-orthogonal frequency division multiplexing(OFDM) systems.

This paper considers the design of iterative receivers for space-frequency block-coded orthogonal frequency division multiplexing (SFBC-OFDM) systems in unknown wireless dispersive fading channels.

Since the conventional iterative receiver with symbol-level cancellation(SLC) has high computation complexity,a low(complexity) iterative receiver scheme with bit-level cancellation(BLC) and detection is proposed which can perform bit-level cancellation by decomposing an M-QAM constellation into a linear combination of binary constellations.
