浅海远程水声通信由于水声信道带来的严重多径干扰和衰落, 导致通信速率低、误码率高
以及接收端信噪比低等缺点。针对这一问题, 提出了一种比较有效的M 元线性调频(L FM ) 水声通
信技术。(Remote shallow water acoustic underwater communication channel because of the serious multi-path interference and fading, resulting in lower communication rate, error rate
And the receiver signal to noise ratio and low defects. To solve this problem, we propose a more effective M-ary linear FM (L FM) acoustic communication
ICT.

在对船用陀螺漂移数据建立时间序列模型的基础上，采用卡尔曼滤波算法对捷联陀螺漂移数
据进行了处理，以提高陀螺静态漂移误差系数的估计精度，并把得到的陀螺漂移误差模型实时补偿到捷联系统中，得到了满意的效果。(Marine gyro drift in the data time series model based on the Kalman filter algorithm using inertial gyro drift data were processed to enhance the gyro drift error coefficient of static estimation accuracy, and to get the gyro drift error model for real-time compensation to the inertial system with satisfactory results.)

ZigBee
说明： 提供了三套ZigBee兼容的
平台，为我们的客户提供一种
只需要添加应用的解决方案。
所有的三种解决方案都是建立
在CC2420/CC2520上，而且
有很好的共存性。这些兼容的
平台缩短了产品进入市场的时
间，简化了系统设计和ZigBee
终端产品的验证。(Provided three sets of ZigBee-compliant platform, to offer our customers only need to add the application of a solution. All three solutions are built on CC2420/CC2520, but also the co-existence of good. These platform compatible product to shorten time-to-market and simplifies the system design and test ZigBee end-products.)
