Link Level Simulation of MHN-E System

This paper shows the link level simulation results of the MHN-E system, an enhanced mobile hotspot network system. MHN-E upgraded the specification to obtain twice the data throughput than MHN. The simulator was designed with a fixed-point level and used as a reference for hardware production. We confirmed the transmission performance of MHN-E system in SM mode and SFBC mode through simulation. The performance of the newly adopted polarized antenna is analyzed in cross-permeation condition of the antennas. The experimental result of this paper can be used as a criterion for generating the CQI from the terminal to the base station. The accurate CQI transmission can control the transmission rate according to the downlink channel conditions, thereby improving the overall data throughput.
