摘要
针对 MPT1 3 2 7集群信令采用的 BCH( 63 ,4 8)纠错编码 ,给出了它的编码方法及检错原理 ,提出了纠正 2位随机错误和 4位突发错误的快速算法 ,与经典的迭代算法相比 ,运算速度提高了 1～ 3倍 。
BCH(63,48) error correcting code is used for MPT1327 trunking signaling. Its coding method and error checked theory is given. A kind of quick algorithm correcting 2 bit random errors and 4 bit abrupt errors is offered. This algorithm can increase the running speed 1 to 3 times than the classical iterative algorithm. It has been used successfully in the Wireless Access Network developed by us.
