The invention discloses a carrier communication signal quality detection and evaluation method and an implementation device thereof, and the method comprises the steps: employing an antenna of a radiofrequency receiving and transmitting module to receive an input signal, and converting an analog-to-digital format into a data string; using an FPGA development board for being in butt joint with a radio frequency receiving and transmitting module and an upper computer. Based on the FPGA development board, modular software simulation of interference resistance, modulation, sending diversity and space-time coding, inverse Fourier transform, detection frequency offset estimation, Fourier transform, phase tracking, receiving diversity and space-time coding, demodulation reduction, screening, conversion, entry estimation and judgment is carried out on input signals according to the difference of transmission signal types. Demodulated data is input into the upper computer, the bit error rate is calculated, and a detection evaluation result is fed back. By applying the monitoring and evaluating solution provided by the invention, a hardware device of a traditional scheme is replaced, so that the cost is greatly optimized, the upgrading and maintenance of finished product functions and a detection and evaluation range are facilitated, and the large-scale signal detection under various application scenes is also facilitated.
Description
technical field [0001] The present invention relates to a communication signal detection and evaluation method and implementation device, in particular to a carrier communication signal quality detection and evaluation method and implementation device based on a simple development device and software simulation, belonging to the technical field of wireless communication. Background technique [0002] With the continuous development and rapid change of communication technology, there are currently tens of thousands of satellites floating in space, communication base stations all over the place, and routers with more dense connections. The application of wireless data transmission has been widely integrated into people's lives, from home PCs, tablet computers, smart phones, Bluetooth digital devices, and even more smart home appliances that are integrated into family life. [0003] Although the frequency bandwidth of carrier communication is quite high, the current mainstream ...
