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 ...

Let S be the set of all binary vectors of length n and weight at most t + 1. Then. S = ∑ i = 0 t + 1 ( 2 m − 1 i). Let H be the parity check matrix. If x is any binary vector of length n, then the syndrome H x T has m t binary components.
WebSep 25, 2013 · BCH codeword are encoded as C (x) = x n-k * i (x)+b (x) (6) for l 1, thus generated polynomial g (x) of binary t-error correcting Where C (x) = c0 + c1 x + + c n-l xn-l BCH code of length given by eqn. (1) can be reduced to g (x) = LCM {1 (x),2 (x),….,2t-1 (x)} (2) BCH code generated by primitive elements is given in [8]. Webextending or shortening, BCH codes with any distance and any length can be constructed. Example Construct a code with length =24 and distance =6. 1) %Take =5 and construct a BCH code with =2 %−1=31 and =2 −1−2∙5=21 ( =2) to get a code with UVW =5. 2) Extend the constructed BCH code to get =32 , =21 , =6.
