AboutVLABS
Abstract— We propose a simple speech compression algorithm
using subband division and ADPCM (Adaptive Differential
Pulse Code Modulation) algorithm. Although speech data are
stored in a semiconductor memory device, its capacity and the
available network capacity are limited. Therefore, it is necessary to
compress the data as much as possible. The first is that the
reconstructed datum must be understood correctly. Speech signal is
compressed with a ratio of 1/4 using the proposed subband division
and ADPCM (Adaptive Differential Pulse Code
Modulation) algorithm.

JPDA
在运动的位置叠加噪声。进行JPDA概率数据关联及kalman滤波。
两运动目标在x-y平面做匀速直线运动。初始位置是(4000,1200)(300,1500)速度分别是(200,200)(400,200)传感器对量目标进行位置状态量测。
采样间隔T=1,点数n=80.检测概率为1,正确量测落入跟踪内的概率为0.99,杂波均匀分布的密度为2个/km2由RAND函数产生在[0,1]上均匀分布的随机变量,跟踪门限为9.21。
