【摘要】 分析了突发模式的通信体制特点,对采用OFDM技术的高速数据传输系统进行了设计,建立了系统基带发射模型和基带接收模型,重点研究了其中的两项关键技术:同步和信道估计,提出了能够满足突发系统要求的实现算法,并分别通过仿真验证了可行性;最后,在AWGN信道和衰落信道条件下,对运行上述算法的系统进行了综合仿真,给出了系统的误码率性能。更多还原

【Abstract】 In this paper,we analyze the burst characteristic of communication system,design high-speed data transmission system based on OFDM,build the baseband models of transmitter and receiver,and especially research two key technologies that is of synchronization and channel estimation.For this,we propose the corresponding arithmetic that can satisfy the requirement of burst communication systems based on OFDM,and the simulation result can testify the feasibility of arithmetic.Finally,on the AWGN channel and the multi-path fading channel,we implement integration simulation for system that operates the above-mentioned arithmetic,and present the bit-error-rate performance of the proposed system.更多还原
