A brief look at Forward Error Correcting codes
Xiaoxue Yang, Yue Wang · 2011
Forward Error Correcting codes are the codes applied in error correction in the communications, by adding redundancies. Without a feedback channel, it is an attractive alternate of ARQ in long delay path and one-way transmission. FECs could also avoid multicast problems. However, in practice, FECs could be relative inefficient due to the expensive cost of computation and requirement of over-transmission sometimes. Hence, in the random error or the burst error channel, particular FEC scheme should be used correspondently.
