| 7 | In this paper, we consider the FPGA implementation of a modied sphere detection algorithm. We analyze |
| 8 | breadth-rst and depth-rst search in sphere detection, and |
| 9 | compare the relative performance and complexity. Based on these comparisons, we propose a more efcient and less complex |
| 10 | scheme, Dynamic Threshold Sphere Detection (DTSD), which can effectively increase the throughput and reduce the error |
| 11 | rate. We, then, propose a novel architecture for this scheme, and discuss the complexity reduction techniques that we utilized. |
| 12 | These techniques do not compromise the overall performance. Finally, the high throughput FPGA implementation results of |
| 13 | this algorithm will be presented. |
