hello,now iam using the 6455 TCP2,but i have a question.i followed the tcp2 standalone example to write my program.i am quite sure that the configuration about the TCP2 is right and the input data format is (4.2)format ,interleave table and the tail data is also ok,I am sure,they are all right.
but i use the TCP2 to decode some encoded turbo code with rate 1/3,3GPP2 standard ,they are not right.
first ,i test framelength 40,the code is ideal for it didnot add any noise,the result is right,i tested it for nearly 20 times.
second ,i test framelength 65,the code didnot add any noise,too,but the result was not right,usually it would have 2 bits wrong .i tested it for nearly 10 times.
third,i test framelength 128,the result was the same with the framelength 40 ,usually it would have 2 bits wrong,and the wrong place changed quickly ,i tested it for nearly 20 times.
last third,i test framelength 1018,the result was the same with the framelength 40 ,usually it would have 2 bits wrong,and the wrong place changed quickly,but usually the fist 100bits was right.i tested it for more 20 times.
now i am quite confused,i wonder what the reasion was,i haved already being keeping find the possible reasion for days,but i failed,i am looking forwads to your help!!!
thank you very much!
