Abstract

In recent years, new communication technologies has made rapid development. Orthogo-nal Frequency Division Multiplexing (OFDM) is a core technology in the fourth-generation wireless communication field(4G). The basic principle of OFDM is to split a high-rate data stream into a number of lower. In OFDM system design, a number of parameters are up for consideration, such as the number of subcarriers, guard time, symbol duration, subcarrier spacing, modulation type persubcarrier, and the type of forward error correction coding. The choice of parameters is influenced by system requirements such as available bandwidth, required bit rate, tolerable delay spread, and Doppler values. This paper designs and implements an OFDM receiver system. The system includes interleaving and de-interleaving module, RS encoding and decoding module, QPSK modulation and demodulation module and some system composed of a number of auxiliary modules. This paper analyses and tests efficiency and other factors of the system, and demonstrating the use of FPGA technology enables to receive signal in the OFDM system so well. It has some advantages of occupying less hardware resources, fast running and having good stability.
