摘要:
为了提高异构网络融合中不同空中接口接入情况下链路性能预测的准确性,提出了基于接收比特互信息率(RBIR)的物理层抽象算法.物理层抽象算法通过压缩函数把一组不同的信干噪比(SINR)序列映射成单一的SINR值,通过该SINR值查表得到真实的误块率(BLER)值.利用拟合函数表示不同条件下的参考曲线表,简化了系统设计的复杂度.从信息论的角度对接收比特互信息率RBIR算法进行理论推导,证明了接收比特互信息率RBIR与误块率BLER具有一一对应的关系.通过对CDMA EVDO网络和无线局域网(WLAN)进行仿真,结果表明,该算法能够较好地描述这2种网络中不同调制编码方式、信道状况和误块率之间的关系,拟合函数曲线与实际仿真结果吻合较好,能够准确预知不同网络的链路性能.
Abstract:
To improve the accuracy of link performance prediction in the case of different air interface access for the integration of heterogeneous network, the physical layer abstraction algorithm based on RBIR(received bit mutual information rate)is proposed. The physical layer abstraction algorithm maps a set of different SINR(single to interference noise ratio)values to a single SINR value, then the BLER(block error rate)value can be achieved by lookup table with the single SINR value. The fitting function instead of the reference curve table with different conditions simplifies the complexity of the system design. From the perspective of information theory, theoretical derivation of the RBIR algorithm is given, and one to one corresponding relationship between RBIR and BLER is shown. Through the simulation of CDMA EVDO network and WLAN(wireless local area network), results show that the RBIR algorithm can better describe the relationship between modulation coding, channel conditions and block error rate; the fitting function curves can fit the actual simulation results well; the algorithm can accurately predict the link performance of different networks.
