Short Desc. : Rate 1/2 Turbo Convolutional Code For 802.16d
Overview :
The Turbo convolutional code for 802.16d uses two parallel concatenated Double Binary Circular Recursive Systematic Convolutional Codes (DBCRSCC) as constituent codes. The advantages of DBCRSCC includ better convergence and better performance, especially with short code at high SNR and high code rate, than a single binary Turbo convolutional code. The error floor of the code is so low that quasi error free decoding is possible with limitted number of iterations. The circular state transition property eliminates the need for tail ending data and hence achieving higher data rate than a single binary Turbo convolutional code.
