Abstract

The invention discloses a method and a device for realizing a link simulation and system simulation interface. The method comprises: obtaining a measured signal to noise ratio of corresponding time slots of encoding blocks in link simulation according to numerical calculation; calculating a measured signal to noise ratio of the encoding blocks according to the measured signal to noise ratio of the corresponding time slots; and calculating corresponding block error rate according to the measured signal to noise ratio of each encoding block and obtaining corresponding relation between the measured signal to noise ratio and the block error rate, and using the corresponding relation as the interface for the link simulation and system simulation. The method and the device can generate an interface through less link simulation and precisely reflect the corresponding relation between the link simulation and the system simulation, thereby efficiently realizing the performance of a link simulation and system simulation cooperation evaluation system.

Description

technical field [0001] The invention relates to the field of computer and communication technologies, in particular to a method and device for realizing a link simulation and system simulation interface. Background technique [0002] In existing mobile communication systems, due to the complexity of the air interface, it is difficult to use theoretical analysis methods to evaluate performance. Therefore, Monte Carlo simulation (a random sampling simulation algorithm) is usually used to simulate the performance of the air interface. Using simulation calculations to evaluate a specific algorithm or optimize specific system parameters can greatly save time and investment for on-site testing of mobile communication systems. [0003] There are two commonly used simulation methods, link simulation and system simulation. Link simulation performs chip-level operations, and outputs system frame error rate (FER, Frame Error Rate) or bit error rate (BER, Bit Error Rate) parameters in...
