Abstract

A device for simulating a shortwave channel comprises a master control module, at least one second operation module and a third operation module. The master control module is used for calculating the number of paths in the shortwave channel and allocating a part of paths to the second operation modules. Each second operation module is used for calculating delay time and grain of each path and accomplishing Doppler spreading and frequency-shift calculation according to Doppler spreading parameters, provided by the third operation module, of the paths. The third operation module is used for providing the Doppler spreading parameters for the paths in the second operation modules. The invention further discloses a method for simulating the shortwave channel and a microprocessor.

Description

technical field [0001] The invention belongs to the technical field of channel simulation, and in particular relates to a method, device and processor for simulating a shortwave channel. Background technique [0002] At present, the shortwave channel simulator mainly uses a single-core digital signal processor (DSP, Digital Signal Processor) or a field-programmable gate array (FPGA, Field-Programmable Gate Array) as the core processing module. However, with the development of communication technology, the existing narrow-band shortwave channel simulators can no longer meet the bandwidth requirements of communication systems, and with the increase of communication system bandwidth, the amount of data that needs to be processed also increases. Therefore, it is necessary to select the theoretical model of the broadband shortwave channel simulator and increase the computing speed of the core processing module. Contents of the invention [0003] In view of this, an object of t...
