Group Turbo Code Technology Research And Dsp Applications

In this subject, we designed the correct encoding and decoding code apply in DSP transmitting in wireless ATM . It is the digital signal processing unit of some system. It's main job is controlling the wireless ATM cell transmitting correctly. Consider the demand of the subject ,we choose the 32×32 BCH product code for block Turbo code encoding project and use "REDDY-ROBINSON"arithmetic and GMD arithmetic and improve them for practice in the decoding project.. we apply it on DSP TMS320C6416 in the system. In this article, firstly ,we introduce correcting encode theory , then we tell something about software and hardware impolder environment .thirdly we introduce the process of applying the arithmetic. Lastly, we give out the performance. Consider applying in project , we discuss some problem about the transmitting of wireless ATM cell . we do mainly job in the subject ,such as : 1. comprehending the error controlling problem in the encode and decode algorithm, they are mostly about iterative and soft decisions decoding algorithm in the block turbo code decoding. 2. basing on the requirement of the system, choose the encoding ande decoding algorithm for the project.. 3. programming for emluator and providing the emulating data . 4. basing on the project, rebuild the algorithm, and apply it on TMS320C6416. 5. debugging the syetem. 6. beginning the error test.
