摘要

正交频分复用技术(OFDM)是一种适用于Raleigh衰落和ricy衰落环境的鲁棒传输技术。对OFDM研究日益增长的兴趣促使我们提出了用于卫星通信的OFDM。本文根据铱星系统给出的技术规范，研究了基于正交频分复用技术的栅格编码调制和turbo编码技术。用L和Ka波段分析误码率(BER)性能。与卷积编码和栅格编码OFDM系统相比，Turbo编码OFDM具有最好的性能。采用部分发射序列技术可将峰值平均功率比(PAPR)降低约1.6 dB。

Performance of turbo and trellis coded OFDM for LEO satellite channels in global mobile communications

Orthogonal frequency division multiplexing (OFDM) is a robust transmission technique in a Raleigh fading and Rician fading environments. The growing interest in OFDM research motivated us to propose OFDM for satellite communications. In this paper, trellis coded modulation (TCM) and turbo coding are considered with OFDM for a Rician fading channel according to the specifications given by the Iridium system. Bit error rat (BER) performances are analyzed with L and Ka bands. Turbo coded OFDM gives the best performance compared to convolutional coded and trellis coded OFDM systems. Peak to average power ratio (PAPR) can be reduced approximately by 1.6 dB with the help of partial transmit sequence technique.
