摘　　要：提出一种新型的基于TDMA的无线网络接入模型。该模型采用嵌入式系统控制,支持多种网络协议,具有灵活的扩展特性,实现远程网络管理与远程软件升级,支持多种编码方案和加密功能。系统使用低功耗的连续相位调制技术(CPM)和复杂度低的复合网格CPM技术,同时采用RS级联TCM的CPM分块编码调制方案,使数据在传输时有纠错编码的保护,且没有扩大频谱带宽。Based on TDMA, a new kind of wireless network model which connects LAN to satellite is put forward. The model is controlled by an embedded system and provides multi-protocol. It has flexible expandability, and can be managed to upgrade softwares by remote hosts. It also provides functions of multi-code and cryptogram. This wireless system uses CPM technique which only needs low power supply, and composite trellis CPM technique which has a low degree of complication. It also adopts BCM formed by the RS code concatenated TCM, which enables the transmilted data to be protected by corrected code and does not expand the band.
