| Abstract: | This paper researched the flow of sphere decoding algorithm and two common algorithm of initial radius selection,and a new type of sphere decoding algorithm based on threshold is proposed.This new algorithm,considering the influence of signal-to-noise ratio and channel condition number on detection algorithm,has lower sphere decoding complexity and ensures performance of sphere decoding.This algorithm has been applied to the LTE-TDD wireless integrated test instrument. |
