摘要
A method of transforming a serial scrambler to a parallel scrambler, a parallel scrambler and a double-edge-triggered register with XOR operation are provided. The method transforms a serial scrambler to a parallel scrambler according to a characteristic polynomial:; ]]> The method first determines a transformation formula:; ]]> according to the parameters of the characteristic polynomial. The parallel bits Bj=[bMj, bMj+1, . . . , bMj+M−2, bMj+M−1] are arranged in order. The transformation number R=2t (the initial number of t is 0) is set. The parallel bits are replaced by the transformation formula. When (k−R)N+i+R(N−q) is larger than Mj−1 in the transformation formula, 1 is added to t in the transformation formula R=2t and the transformation formula is re-counted. Finally, the XOR gates are connected to the registers according to a computed result from the transformation formula.
