Simplified MD-LSD demapping algorithm for BICM-ID systems with multi-dimensional mappings
The soft in soft out MAX-LOG-MAP algorithm of conventional mappings was expanded to the BICM-ID sys- tem with multi-dimensional mappings. A multi-dimensional list sphere decoding (MD-LSD) algorithm was also proposed by using the list sphere decoding algorithm of multi-antenna systems. Compared with...

description | The soft in soft out MAX-LOG-MAP algorithm of conventional mappings was expanded to the BICM-ID sys- tem with multi-dimensional mappings. A multi-dimensional list sphere decoding (MD-LSD) algorithm was also proposed by using the list sphere decoding algorithm of multi-antenna systems. Compared with the MD-MAX-LOG-MAP algo- rithm, the computational complexity of MD-LSD was decreased significantly. Simulation results show that the perform- ance degradation of the simplified MD-LSD algorithm can be ignored when the list length is in a certain range. |
