摘要:
提出了一种准时隙ALOHA-CDMA信道,作者将其称之为应答式ALOHA-CDMA信道,给出了这种信道的模型,推导了在子系统内部由于碰撞冲突对传输性能的影响,给出了这种准时隙ALOHA-CDMA信道的检测概率.结果表明:这种系统不但可以简化设备,还可以显著提高网络的接收机检测概率和信道利用率,对于卫星VSAT系统、地面分组无线网络等具有实用价值.
Abstract:
A k ind o f acknow ledgment- type Slotted-ALOHA-CDMA channe,l w hich is called ACK-ALOHA-CDMA channel by the auther, is stud ied in this paper. The channe lm ode l is g iven firstly. Then the in terference between subsy stem s is obta ined and the transm ission influence in subsystem s is discussed. F inally, detecting probability is obta ined. Sim ulation resu lts show that a sign ificant perform ance im provem ent can be gained by using acknow ledgment- type Slotted-ALOHA- CDMA channel in sate llite VSAT system s and rad io packed netw orks w ith low comp lex ity and h igh-bandw idth eff-i c iency.
