  sphere decoding
Recently, a sphere-constrained maximum-likelihood detection, so-called sphere decoding, has drawn much attention for reducing the computational burden in MIMO transmission systems.
      
This paper describes the super-trellis structured Viterbi algorithm applying per-survivor sphere decoding, and evaluates the effect of the complexity reduction in branch metric computations.
      
According to the architecture discussed above, the sphere decoding is actually an iterative process.
      
A recap of the sphere decoding algorithm as well as an introduction to the parallel implementation are given in Section III.
      
As the procedure to find these vectors is quite laborious, the sphere decoding alternative is still rather complex.

Complexity of ML(Maximum Likelihood) joint detection using exhaust search increases exponentially as input length.Sphere decoding becomes a hot spot because it can achieve ML performance in complexity of polynomial. We propose in a new reduced complexity decoder for CDMA(Code Division Multiple Access) system based on LS code. Compared to the original algorithm, this algorithm has lower computation complexity and is more insensitive to the choice of initial radius. Simulation indicates the complexity can reduce to half of that of original one. Thus, by making the choice of radius sufficiently large, the ML solution is guaranteed with low complexity, even for large constellations, this algorithm is optimal for LAS-CDMA system in the sense of ML.

利用穷搜索的ML(MaximumLikelihood)联合检测其复杂度随输入长度指数增长,因而在实际系统中很难实现。为此,提出一种用于LAS-CDMA(LargeAreaSynchronousCodeDivisionMultipleAccess)系统联合检测的球译码算法。与原始算法相比,该算法具有更低的复杂度。仿真表明,该算法复杂度能降低大概一半。对初始半径的选择敏感性更低。在初始半径的选择足够大时,即使对于大的调制星座,也可在保证低复杂度的同时取得ML解,对于LAS-CDMA系统,该算法在ML的意义上是最优的。

In this paper, we adopt a special kind of rotation matrix and circulation matrix to construct space-time block codes for MIMO (Multiple Input and Multiple Output) systems with equal transmitting antennas and receiving antennas, the effective channel model is derived and sphere decoding method is used for this scheme. Simulation shows that our scheme achieves the performance similar to some known optimal space time coding scheme.
