A System View on Iterative MIMO Detection: Dynamic Sphere Detection versus Fixed Effort List Detection
Table 5
System perspective constraints for different scenarios for antenna, 64-QAM systems. The resulting throughput, area, power, and communications performance are very dynamic. Two different types of scenarios are analyzed: communications centric and throughput centric. The fixed effort list detector consists of one fixed effort detector and two LLR units.
