Recent reports on digital communications have shown that the use of Sphere Decoding(SD) in multiple antenna system can achieve maximum
likelihood performance with low complexity. Although there were lots of
proposals of reducing the computational complexity of SD, since
the computational complexity of SD is probabilistic,the analysis on the complexity of SD was based on the average number of complexity's distribution. However when a real time processing is needed, occurance probability of prohibitively high complexity, namely, behavior of the tail of complexity's distribution is significant. For that reason, in this report we examine and discuss the cumulative distribution of the complexity of search algorithm in SD. From the simulation's results, we understood that the computational complexity's distribution of Pohst and Schnorr-Euchner search algorithm used in SD and its tail behavior is greatly rely on the composition of the system. |
