Technology Research of More Double Compensation of Weak Signals in Communication in 2.4 G Wireless Communication System

传统的2.4G通信网络在远距离通信中,具有较高的成本,在通信信号衰减与干扰的状态下造成的通信延迟。为此,提出一种2.4G通信网络弱信号补偿通信方法,采用反算子补偿干扰性突变对2.4G通信信号频率和振幅的衰减,在时间域对2.4G多点无线通信系统中的弱数据进行高频补偿提取操作,采用最小均方误差规范设置线性时不变的滤波算子,从被干扰的信号中获取最优预测源信号,消除速度效用引起的干扰,通过补偿算法对变质的弱信号进行再次补偿,确保2.4G多点无线通信信号的顺利传递。实验结果说明,该种方法对2.4G多点无线通信由于速度效应而产生畸变的弱信号得到了较好的补偿,对白噪声信号的补偿效果优于传统方法。

Put forward a kind of weak signal compensation 2.4 G communication network communication method, the inverse operator compensation disruptive mutation of 2.4 G communication signal frequency and amplitude attenuation, in the time domain of 2.4 G wireless communication system more weak data extraction operation, high frequency compensa- tion adopts the minimum mean square error norm set of linear time invariant filtering operator, to obtain the optimal prediction in from the interference signal source signals, to ,eliminate the influence of speed caused by utility, again through the compensation algorithm of the metamorphism of the weak signal compensation, to ensure the 2.4 G wireless signal more smoothly. Experimental results indicate that the approach of 2.4 G wireless communication more produces weak signal distortion due to speed effect got better compensation, compensation effect is superior to the traditional method Of white noise signal.
