Abstract
Multipath effects usually occur in information dissemination, which leads to inter-symbol interference and affects the quality of communication transmission. This paper uses an adaptive equalizer to achieve channel equalization and eliminate inter symbol interference, and develops and verifies it on the FPGA using the ISE suite. Compared with the equalizer output error signal calculated on the MATLAB software, the calculation results of the two platforms are basically the same, which confirms that the design is feasible. The FPGA-designed equalizer implements hardware acceleration and is more suitable for high-speed real-time signal processing. After the data passes through the adaptive bit equalizer, the signal-to-noise ratio is improved, thereby reducing the bit error rate and verifying the relationship between the bit error rate and the signal-to-noise ratio.
