dc.description.abstract In this paper, we consider the FPGA implementation of a modified sphere detection algorithm. We analyze breadth-first and depth-first search in sphere detection, and compare the relative performance and complexity. Based on these comparisons, we propose a more efficient and less complex scheme, Dynamic Threshold Sphere Detection (DTSD), which can effectively increase the throughput and reduce the error rate. We, then, propose a novel architecture for this scheme, and discuss the complexity reduction techniques that we utilized. These techniques do not compromise the overall performance. Finally, the high throughput FPGA implementation results of this algorithm will be presented.
