Fast Parameter Estimation Algorithm for Punctured Convolution Code
Zhitao Huang · Journal of China Academy of Electronics and Information Technology · 2013
The punctured convolution code has been widely used in adaptive modulation and coding technology and multilevel coding systems for its characteristic of simple structure,alterable code rate and flexible decoding.A generator matrix characteristic searching based fast parameter estimation algorithm for blind recognition of punctured convolution code is proposed,the algorithm reduces searching range greatly by making a lot use of the characteristic of punctured convolution code generator matrix.Simulation result verifies the validity of the proposed algorithms and computational load is less than the algorithm in literature.
