摘要:
本文分析了加性白高斯噪声(AWGN)信道中改进的帧同步捕获方案的性能,并通过数值计算和计算机模拟,与一般的二进对称信道(BSC)的相关帧同步捕获方案和AWGN信道中的相干帧同步捕获方案进行了比较。结果表明改进方案的首次捕获概率性能优于其他两种方案。如若要求首次捕获概率大于0.95,采用长度为17的最佳帧同步码,改进方案在信噪比要求上比BSC的相关方案好2.5dB,比AWGN信道中的相干方案好6.7dB。文中还给出了计算机模拟和搜索最佳帧同步码的程序框图,给出了部分最佳帧同步码,可用于各种实际情况而能得到良好性能。
Abstract:
The performance of the modified algorithm for frame sync acquisition on the AWGN channel is analyzed and compared with the correlation algorithm on the BSC and the coherent algorithm on the AWGN channel for frame sync acquisition by numerical calculaton and computer simulation. Results show that the modified algorithm is better than the other two in first frame syne anquisition probability P_{A_{1}P}·If P_{A_{1}P}>0.95 is required and optimum frame sync codes with length of 17 are used, the modified algorithm is superior to the correlation algorithm on the BSC and the coherent algorithm on the AWGN channel in signal-to-noise ratio by 2.5 dB and 6.7 dB, respectively. Flow diagrams of the computer simulation program and the searching program for optimum frame syne codes are presented, a subset of optimum frame sync codes is listed for practical use with fine performance as well.
