There are some Constraints such as moving as planned trajectory when industrial robots perform tasks. Then we should make trajectory planning which can improve the precise and stability of the robots movement, so it is very crucial to do research on industrial robots trajectory planning. This thesis concentrates on the research on the trajectory planning

Masking effect is an important psychoacoustic phenomenon. It is a process that thethreshold of one sound is raised for the emergence of another sound (maskee). Suchphenomenon has important application values in sound information science such as audiocompression algorithm, speech enhancement, information hiding and so on. One hundredyears have passed since Wegel and Lane published their

In the standard based on IEEE802.16d, an air interface criterion for fixed broadband wireless access systems is prescribed. The OFDM is a multi-carrier transmission technique used by IEEE802.16d, which is of high utilization efficiency of frequency spectrum and resistant for multi-path. The thesis mainly investigates and implements synchronization and channel estimation technologies in OFDM systems
