Flexible Decoder Based on MAP-Algorithm for Two Different Families of Codes
Many wireless communication systems such as IS-54, EDGE, WiMAX and LTE have adopted turbo codes and tail-biting convolutional codes as the Forward Error Correcting-codes (FEC) scheme for data and overhead channels. However, some releases propose LDPC codes for error-corrections due to the relative complexity of turbo codes decoder implementations as well as the success of LDPC codes in achieving the same performance as turbo codes and in some cases surpassing it with low decoding complexity.
