Establishment of Channel Coding Test Platform

In order to obtain the actual performance of channel codec,a channel coding test platform based on hardware was established.The design scheme is presented,and a modified Gaussian white noise generation method proposed.The chi-square test and K-S test showed that the generated samples complied to Gaussian distribution.The sharp characteristic of the auto-correlation function of the samples and approximate constant value of the power spectral density showed that the samples had the white noise property.The test platform is implemented on field programmable gate array(FPGA),and application results showed that the test platform implemented can be used as a digital hardware test tool for channel codec or new decoding algorithms.
