What is a turbo code?
- The turbo code, as described in Chapters 3 and 4, is a very complex channel coding scheme. The turbo code encoder is a parallel concatenation of two recursive systematic convolutional (RSC) codes. The turbo code decoder is an iterative serial concatenation of two soft output Viterbi algorithm (SOVA) decoders.
What are the advantages of a turbocharger?
- Note: this turbo is suitable for 125cc to 600cc engines. There will not have enough air flow to push the turbo to generate meaningful boost if engine is too smaller. The turbocharger can increase the air flow of engine intake, add the power and torque, and improve the performance of engine. 1 Characteristic 1.1 Picture of Turbo
What is the smallest turbocharger?
- This turbocharger is the smallest turbo in the world, very similar to the IHI RHB31 turbocharger. This turbo is ideal for turbocharging your Motorcycle, scooter, dirt bike, ATV, go kart, buggy, and snowmobiles. Note: this turbo is suitable for 125cc to 600cc engines.
Is turbo code decoding better than Viterbi?
- From Figures 5.6, 5.7, and 5.8, it can be seen that turbo code decoding is able to provide comparable or better BER performance for small constraint length codes (e.g. K=3 or K=4) than Viterbi decoding of large constraint length codes (e.g. K=5 or K=6) under the condition that relatively large frame sizes (FS ? 192 bits) are used.
