摘要
介绍了FM IBOC DAB系统中抗第一邻频干扰和无线信道噪声、衰落等干扰的主要技术,包括加扰、CPPC码纠错、交织和正交频分复用调制,最后提出了一些新的抗干扰措施,进一步提高了信道的鲁棒性能。
The main technologies that resist interferences such as the first adjacent FM interference, the noise and fading in the FM wireless channel are described. Scrambling, CPPC encoding, interleaving and OFDM modulation are included. Finally, some new anti-interference technologies that can improve the robustness of channel are presented.
