Investigation on Simulation-Number in AWGN Channel

Investigations on principle of Monte Carlo simulation was made when considering characteri-(stics) of AWGN(additive white Gaussian noise) channel and the affects of three suitable parameters: error number,confidence probability and max relative error of simulation result.And common conclusion was reached: error number would present direct ratio to square of confidence upper limit,on the other hand,inverse ratio to square of max relative error.The result of computer simulation demonstrates that the conclusion is effective under conditions of AWGN channel.Under conditions of fading multipath channel,if some techniques such as OFDM(orthogonal frequency division multiplexing),diversity,equalization,and interleaving were used to turn channel into AWGN channel,the conclusion will be also effective.
