WPAN系统容量分析及改善

Capacity Analysis and Enhancement of Capacity in WPAN System

对采用跳频扩频方案的无线个域网标准的系统容量进行了分析,在此基础上,提出了采用包长度自适应控制技术来提高系统容量的方法,并以跳频扩频的蓝牙系统为例,分析了蓝牙ACL包和SCO包采用自适应包长度控制技术与固定包长度传输时的系统容量变化.仿真结果表明,采用该方法能够有效地改进系统的容量性能.

An adaptive control method of packet length is presented in this paper in order to im-prove the capacity of WPAN. This technique is based on the analysis of system capacity in WPAN standard, which uses FHSS schemes such as Bluetooth. A comparison of system capacities be-tween adaptive packet length and fixed packet length has been made for the case of ACL link and SCO link of Bluetooth. Simulation results show that the adaptive packet length algorithm can im-prove the capacitv of WPAN effectively.
