Multiple antenna systems are a promising approach to increase the data rate of wireless communication systems. There exist two main transmission schemes. In BICM systems, modulated symbols are multiplexed on multiple transmission antennas while an outer error correction code ensures the desired quality of service for a given data rate. Space-time trellis codes use a trellis structure to determine...
Energy-efficient realization of soft-output signal detection is of great importance in emerging high-speed multiple-input multiple-output (MIMO) wireless communication systems. This paper presents three algorithm-level complexity-reduction techniques for soft-output detector design to achieve significant energy savings. To demonstrate their effectiveness, we designed a soft-output detector for 4-4...
