Performance Analysis and Simulation of BCH(63,56)

BCH(63,56)is widely used in uplink channel of deep space communication for low-complexity implementing,which can check 2 bits error and correct 1 bit error. The performance of BCH(63,56)is studied by theoretical analysis and computer simulation in this paper. On the basis of introducing the basic principle of BCH(63,56),the performance of bits error rate is calculated and the Monte Carlo simulation is carried out. The results show that the coding gain of BCH(63,56)can be up to 2.1 dB when the bit error rate is 1e-5.
