Original Title: Turbo Codes.ppt. Uploaded by • To attain high performance, channel code employed must be high power, such as powerful low density parity check (LDPC) codes or turbo codes – These powerful channel codes have high decoding complexity – Simple RSC CC(2,1,2) however could not offer high performance • Alternative: use simple code, e.g.

Turbo Codes RS/Convolutional codes, used in line-of-sight links as a form of SCCC. A Turbo SCCC may look like the figure below with different rate constituent codes. EC1 S EC2 Rate 1/2 Rate 2/3 Figure 2 – Serially concatenated constituent coding (SCCC) Then there are also hybrid versions that use both PCCC and SCCC such as shown in figure below. EC2 EC3 The first class of turbo code was the parallel concatenated convolutional code (PCCC). Since the introduction of the original parallel turbo codes in 1993, many other classes of turbo code have been discovered, including serial versions serial concatenated convolutional codes and repeat-accumulate codes. Iterative turbo decoding methods have the code.
