Based on an extrinsic information transfer (EXIT) chart assisted receiver design, a low-complexity near-maximum a posteriori (MAP) detector is constructed for high-throughput MIMO systems. A high throughput is achieved by invoking high-order modulation schemes and/or multiple transmit antennas, while employing a novel sphere detector (SD) termed as a center-shifting SD scheme, which updates the SD's...
We analyze MIMO systems where either Bit-Interleaved Coded Modulation (BICM) by itself or in concatenation with Space-Time Block Codes (STBCs) is used at transmission, assuming iterative Turbo-like decoding at reception. We employ Serially-Concatenated Low-Density Generator Matrix (SCLDGM) codes specifically optimized for each system configuration, and focus on two relevant STBCs: the Golden code,...
In this paper, a novel approach using frame-based iterative channel fading parameters estimation technique from the received data sequence exploiting orthogonal property of the space-time block (STB) code is proposed. For practical implementation of STB code, the receiver requires to estimate these parameters. Regarding this type of estimation, the inherent orthogonal nature of STB code can be exploited...
