The bit error rate is an important indicator for evaluating the data transmission equipment and its channel quality, while the bit error tester, as a tool to test the reliability of a communication system, is widely used in the production, testing, inspecting and maintenance of transmission equipment. In this paper, a bit error tester for digital baseband communication systems over Gaussian fading channel is designed, and the corresponding test of bit error rate (BER) performance can be realized. By means of FPGA experiment platform, the production of the digital baseband signals, constellation mapping, baseband shaping, channel, matched-filter, decision, de-mapping, and the calculation of BER can be realized by programming with Verilog language. Moreover, the resultant BER can be displayed with FPGA.
