Abstract

With the development of communication technology, putting forward higher requirements for the city's communication rate. Due to the complex environment in the city, there is a serious multipath fading effect in the communication process of broadband wireless channel transmission, which has a great negative impact on the transmission of information and greatly improves the bit error rate. In order to overcome the degradation of communication quality caused by multipath effects, communication technology workers have proposed kinds of techniques anti-multipath effects, which also help single carrier frequency domain equalization (SC-FDE) overcomes the effectiveness of multipath fading in digital communications. Therefore SC-FGE has been widely used. This paper introduces the mainstream technology against multipath effect based on the principle of multipath effect, then analyze the design of single carrier frequency domain equalization system in detail, and implements the system on FPGA platform to test the final bit error rate and other indicators.
