Hi, i'm having a problem decoding some convolutionally encoded datas:
Datas are actually encoded with the following polinomials: -x4+x3+1 - (11001) -x4+x2+x+1 - (10111) Decimals for those polynomials are 25 and 23 and based on CC Encoder Definition documentation found on the wiki Costraint Length (K) parameter should be 5 since polynomial grade is 4. I 've tried Encoding and decoding the datas with the default parameters given with the Encoder and Decoder definition (79 and 109 poly and K=7) and everything works fine. When i change the polynomials it won't decode the datas correctly. My thought is that it may be due to the K parameter that should be set to 5 for those polynomials, however, while i can set it to 5 for the encoder with no problems, when i set K param to 5 in the CC Decoder Definition and run the program it will stop running immediatly, printing "Done" without any error message. Trying with other values different from 7 the result is always the same. Execution of flowgraph stops immediatly. I dunno how to set that parameter correctly. Below i'll write how every parameter in encoder and decoder definition is set: CC Encoder: ID= encoder Parallelism=0 FrameBits = 2048 Constraint Length(K) = 5 Rate Inverse = 2 Polynomials = [25,23] Start State = 0 Streaming Behaviour = Terminated Byte Padding = No CC Decoder: ID= decoder Parallelism=0 FrameBits = 2048 Constraint Length(K) = 5 Rate Inverse = 2 Polynomials = [25,23] Start State = 0 End State = -1 Streaming Behaviour = Terminated Byte Padding = No Thanks in advance *Massimo Isonni*
