摘　　要：为了解决多芯片构成的无线芯片域网络(WCAN)中的多用户网络通信问题,进行了WCAN自适应多址调制方案研究。结合WCAN的具体应用场景,首先研究了芯片内/间的无线信道特性,分析了多址跳时-脉冲位置调制(TH-PPM)技术的干扰噪声源及BER性能;然后在此基础上提出了自适应多址TH-PPM方案,设计了智能化的传输机制,以对WCAN中芯片内/间的功率、误码率、传输速率进行权衡;最后通过仿真给出了其性能分析。研究结果显示,该方案在确保芯片内/间无线互连QoS可靠的同时,能够合理地分配系统资源,显著提高系统的传输性能,有效解决固定多址调制技术存在资源分配不均,系统性能不稳定的缺陷。In order to solve the multi-user networking communication problem in a wireless chip area network （WCAN）, an adaptive multiple access modulation scheme for WCANs was studied. According to the specific application scene of a WCAN, the characteristics of the intra/inter chip wireless channels were investigated, and the interference noise sources and the BER performance of the multi-access time hopping-pulse position modulation （TH-PPM） technique were analyzed. Then an adaptive multiple access TH-PPM scheme was put forward, and an intelligent transmission mechanism was designed for balancing the intra/inter chip power, the error rate, and the transfer rate. The performance analysis of the scheme was performed with the simulation. The simulation and computation results show that the proposed scheme could allocate system resources rationally and improve the transmission performance of the system while providing the QoS guarantee, and the effective resolutions of uneven resource allocation and unstable system performanc for fixed multiple access modulation techniques.
