摘要：
Frame synchronization is essential for OFDM systems. In this paper, cyclic prefix based maximum likelihood estimation frame algorithm and pseudo-noise preamble based frame algorithm are implemented on FPGA. By comparison, the performance of the two algorithms on FPGA is simulated under the AWGN channel. The results indicate that the pseudo-noise series (PN) preamble based algorithm is more accurate and resource-saving than the cyclic prefix (CP) based algorithm.
