Physical layer abstraction algorithm based on RBIR for CDMA EVDO and WLAN
2011
A tightly coupled air interface is the key technology for the integration of heterogeneous networks. The information interaction between different layers must be considered when the tightly coupled air interface of the integral heterogeneous networks is researched, which is called cross layer design and optimization. The physical layer abstraction algorithm is crucial to cross layer design. This paper discusses the physical layer abstraction algorithm, investigates the physical layer abstraction algorithm based on received bit mutual information rate (RBIR), and applies the algorithm in the integral heterogeneous network for CDMA EVDO and WLAN. Simulation results show that the algorithm can better describe the relation between modulation coding, channel conditions and packet error rate.
