为了提高移动通信过程中,系统信息服务的可靠度,提出了基于格基改进的优化方法。该方法采用格基算法,改进SDR输出跟踪方法,得到精简且正交的改进优化矩阵,然后对限制条件进行收缩,以减少信道串扰,增强抗噪能力。通过系统仿真对比分析,证明了基于格基改进的可靠度优化方法有效降低了误码率,提高了系统信息的可靠度。
In order to improve the reliability of system information service during mobile communication, an optimization method based on lattice improvement is proposed. This method uses the lattice-based algorithm to improve the SDR output tracking method, and obtains a streamlined and orthogonal improved optimization matrix, and then narrows the restriction conditions to reduce channel crosstalk and enhance anti-noise ability. Through comparative analysis of system simulation, it is proved that the reliability optimization method based on lattice improvement can effectively reduce the bit error rate and improve the reliability of system information.
