Abstract

The invention discloses a heterogeneous network dynamic system level simulation method based on a physical layer abstraction algorithm. Aiming at the heterogeneous network fusion of an LTE (Long Term Evolution) honeycomb mobile communication network and the next generation high-speed wireless local area network based on a Wi-Fi wireless transmission standard protocol 802.11n, link simulation of a complex physical layer is simplified by using the physical layer abstraction algorithm and abstracted into a simple unitary parametric function, details of the physical layer protocol are shielded, and 802.11n and LTE different physical layers are abstracted into a uniform air interface model to be used as an across-layer module. The heterogeneous network dynamic system level simulation method based on the physical layer abstraction algorithm, provided by the invention, realizes dynamic system level simulation and greatly lowers operation complexity.
