To improve the efficiency of transmitting encoded data in wireless channel, the application of turbo codes in coded orthogonal frequency division multiplexing ( cofdm ) is researched in this paper 本文针对无线信道的编码数据传输,研究了turbo码在编码正交频分复用(cofdm)中的应用问题。
The u . s . transmission format is called 8-vsb ( for 8-level vestigial sideband ), which is more susceptible to multipath distortion than the european system, called coded orthogonal frequency division multiplexing, or cofdm 美国的传送格式是八阶残边带(8-vsb),这种格式比欧洲的编码正交分频多工(cofdm)系统,更容易受到多路径问题影响。
A subspace-based blind channel estimator has been developed for space time coding orthogonal frequency division multiplexing ( stc-ofdm ) system with two transmit antennas and two receive antennas 摘要针对使用2个发射天线和2个接收天线并且采用循环前缀的空时编码正交频分复用系统(stc-ofdm),提出了一种信道盲估计算法,并给出信道可被辨识的条件。
This thesis based on europe dvb-t cofdm ( coded orthogonal frequency division multiplexing ) system, does a lot of research from the development, the technique instrument of dttb to the whole dvb-t system structure and system flow . then brings forward its own ideas and optimizing advices after the stimulation of normal dvb-t system . firstly the thesis describes the needed conditions, the technical difficulties and the present problems of dttb 本课题就是基于欧洲dvb-tcofdm系统技术,从当前数字电视地面广播的发展,数字电视地面广播标准的技术手段到完整的dvb-t系统流程,做了一定的研究工作,并根据标准dvb-t系统做了建模仿真和分析,提出了对dvb-t系统的认识和优化设想。
