Research on Spread Spectrum Multi-Target Diversity and Tracking Technology

Research on Multi-Sensor Multi-Target Tracking Algorithm

The tracking performance of JPDA-based algorithms will be decreased with the increase of sensors amount and clutter density. Thus it is necessary to find out a multi-sensor data fusion tracking algorithm which has lower computation and higher tracking accuracy. Since the motion direction of the targer is viewed as a key factor in data correlation, the pseudodirection tracking gate can be improv...

Decentralized and Cooperative Multi-Sensor Multi-Target Tracking With Asynchronous Bearing Measurements

Bearings only tracking is a challenging issue with many applications in military and commercial areas. In distributed multi-sensor multi-target bearings only tracking, sensors are far from each other, but are exchanging data using telecommunication equipment. In addition to the general benefits of distributed systems, this tracking system has another important advantage: if the sensors are suff...

Research on Mine Roadway Communication System Based on Multicarrier Spread Spectrum Technology

The coal information system based on the electric power line was put forward after analyzing briefly the structure of mine distribution power network in roadway underground, connected with communication and monitoring networks existed already. The system uses a multi-level distributed bus network structure, roadway where harsh conditions, using a combination of multi-carrier and spread spectrum...

Spread-Spectrum Multi-h Modulation

Chapter 4 Diversity Reception in Spread Spectrum

Spread spectrum modulation techniques are mostly employed in wireless communication systems. In order to fully understand spread spectrum communications, we need to have a basic idea on the characteristics of wireless channels. The behavior of a typical mobile wireless channel is considerably more complex than that of an AWGN channel. Besides the thermal noise at the receiver front end (which i...
