Accelerated Algorithm for Computing the Weight Distribution of Convolutional Codes, part 3
Yuya Yamanaka, Masakatu Morii (Kobe Univ.), Hiroshi Sasano (Kinki Univ.) IT2010-27
Abstract (in Japanese) (See Japanese page) 
(in English) The weight spectrum is a significant factor to evaluate the performance of convolutional code.
The weight spectrum is obtained by searching a tree, and the cost required for searching a tree increases at an exponential rate in proportion to node level.
Cedervall-Johannesson proposed a fast algorithm called Fast Algorithm for Searching Trees(FAST) in 1989,and authors proposed the improved algorithm called IFAST.
Sasano proposed an efficient algorithm called the Improved Bidirectional Search.
In this paper, we propose an accelerated algorithm for obtaining the weight spectrum, which algorithm is the improvement of the IFAST.
Our proposal method is especially efficient for the detection of the code numbers around the minimum free distance.
