电信系统使用载波,以便通过电缆或无线传输信息。如果每次只发送一个载波,则系统信号将不能幸免于频率选择性衰落。如果频率选择性衰落包括系统的工作频率,那么无线链路将无法建立。正交频分复用OFDM是解决信号间干扰和频率选择性衰落的主要方法。许多载波可以通过将快速信息流拆分为较慢的数据序列来产生。不同的正交频率携带较慢的数据序列。turbo码的使用可以进一步提高系统的性能。Turbo码使系统具有更好的抗噪声性能,具有良好的误码率性能。本文详细分析了一种采用PCCC技术的turbo编码OFDM方案在信道中存在AWGN、相位噪声、Rayleigh衰落、Rician衰落和多普勒频移的情况下的性能。

英文摘要:
  A telecommunication system uses carriers in order to transmit information through a cable or wirelessly. If each time only one carrier is transmitted, then the system s signal will not be immune to frequency selective fading. If frequency selective fading includes the working frequency of the system, then the wireless link will not be established. Orthogonal frequency division multiplexing OFDM is the primary solution for coping with inter signal interference and frequency selective fading. Many carriers can be produced by splitting a fast information stream to slower data series. Different orthogonal frequencies carry slower data series. System s performance can be further enhanced with the utilization of turbo codes. Turbo codes make the system more immune to noise effects with excellent BER results. This paper presents the thorough analysis of a turbo coded OFDM scheme using a PCCC technique in the presence of a channel which includes AWGN, phase noise, Rayleigh fading, Rician fading and Doppler shift.
