WebThe BCH Encoder block creates a BCH code with message length K and codeword length ( N – number of punctures). If the encoder is processing multiple codewords per frame, then the same puncture pattern holds for all codewords. The input and output signal lengths are listed in Input and Output Signal Length in BCH Blocks. WebThe encoding circuit for BCH codes is a binary division circuit while for Reed-Solomon codes, the division circuit is defined over 𝐺𝐹2𝑚, where 𝑚 is the size of the symbol. The addition in the BCH encoder as shown in Fig (a) is binary ‘XOR’ while the addition in the RS encoder in Fig(b) is addition over 𝐺𝐹2𝑚.

WebSep 24, 2016 · For binary BCH codes it appears that, as a rule of thumb, the algorithm is superior to other decoding procedures for codes that correct more than three errors. In this paper an improvement is described. The resulting algorithm requires a somewhat simpler de- coder in that an inversion circuit is not required. Inversion in a finite field is ... WebIn Fig. 4, the testing codes are maintained to be (63, 39) BCH code and (511,493) BCH code, while P e is set to 0.1, 0.01 and 0.005, respect-ively. It can be seen that the PCR increases with the decrease of P e, and P e has greater influence on longer BCH codes than it does on shorter ones. Furthermore, an important conclusion can be deduced ...
